• The two crews sailed different modes in the same wind: Race Team foiled upwind at 12.5-15 km/h for 53 % of the time, Development for 13 %. Development sailed that band mostly in H1 (38 %) and H2 (11 %). Downwind at 12.5-15 both foiled (Race Team 71 %, Development 98 %). Where both crews foiled upwind at 12.5-15, Race Team sailed 52.0 deg at 36.5 km/h, for 23.5 km/h of VMG (10 periods), and Development 56.4 deg at 35.7 km/h (18.2, 4 periods: a pointer), with more twist (21.7 against 15.4 deg) and the jib lead further in (45 % against 57 %). Development's next step in 12-15 km/h is getting up and staying up upwind.
• Upwind on the foils at 12.5-17.5 km/h, Race Team was 2-4 deg lower and 3-5 km/h slower than NZL's best J2 sailing, with less cant and less twist. At 12.5-15 Race Team sailed 52.0 deg at 36.5 km/h, for 23.5 km/h of VMG (10 periods); NZL (Valencia, J1) 49.5 at 41.5 (29.0, 11), SUI (Valencia) 49.9 at 41.4 (27.1, 26) and our own 10 Nov J2 blocks 50.1 at 39.4 (26.0, 24). At 15-17.5: Race Team 43.7 deg at 40.3 km/h (29.6, 18); NZL (Valencia Fri, J2) 40.2 at 44.8 (35.0, 14). Race Team carried leeward cant of 5.1 and 4.1 deg against 1.9-4.6 (- = more) and less twist than NZL and SUI (Valencia): 21.7 and 24.2 deg against 25.8-30.8 (our 10 Nov J2 blocks were 22.9 and 21.9). Above 17.5 km/h it pointed 4-6 deg higher than NZL (Valencia Fri) for 1.7-5.0 km/h less speed and about the same VMG. Try more cant (towards 2) and 26-30 deg of twist on the foils from 12.5 km/h up.
• In H1 upwind at 12.5-15 km/h, Race Team was 5.5 deg higher than Development for 1.2 km/h less speed, and came out 0.8 km/h of VMG ahead. Race Team sailed 53.1 deg at 21.3 km/h, for 13.2 km/h of VMG (7 periods). Development sailed 58.6 deg at 22.5 km/h (12.4, 11 periods). Race Team had the clew much nearer the middle (-170 against -423 mm, - = windward), less twist (16.8 against 23.4 deg), less AWA-E1 (5.8 against 11.0 deg), CA6 less flat (11.1 against 3.8 deg), more cant (4.2 against 5.7, - = more) and the jib lead further in (54 % against 70 %). At 10-12.5 it went the other way, but Race Team had only 4 periods there.
• In H2 upwind both crews matched NZL's best Geneva periods on VMG; Race Team got there higher and slower, and slid more. At 10-12.5 km/h Race Team sailed 46.2 deg at 12.6 km/h (8.6 km/h of VMG, 17 periods), Development 47.4 at 13.2 (8.9, 36), and NZL (Geneva) 51.3 at 14.3 (8.9, 12). Race Team's leeway read 5.5 deg against 3.6-3.7 for Development and Geneva, with more camber (CA1 32.3 deg against 28.7-28.9) and the clew further to windward (-469 mm against -336 and -258). Five on board against four may be part of it. Try 29 deg of camber with the clew nearer -300 mm in displacement.
• Upwind on the foils, Race Team's angle came up steadily with the wind as twist went on and cant came in. 12.5-15 km/h: 52.0 deg at 36.5 km/h (twist 21.7, cant 5.1). 15-17.5: 43.7 at 40.3 (24.2, 4.1). 17.5-20: 39.3 at 41.6 (26.8, 2.9). 20-22.5: 38.7 at 43.6 (28.6, 1.8; 4 periods). This matches the last two days: more twist and more cant come with the faster upwind sailing.
• Development's starts were slow off the line: speed at the gun, not position, was the difference. Race Team's guns 1 and 2 crossed on time at 52.7 and 62.6 km/h, foiling, and reached M1 in 22 s at 61-64 km/h. Development's gun 4 was on time but in RUA at 22.5 km/h and never sailed to M1 (closest pass 194 m), and gun 5 was foiling at 30.5 km/h, 17 m back and 2 s late, and reached M1 in 29 s. Race Team's gun 3 came in the lull, in H2 at 14.2 km/h in 9.6 km/h of wind. Build speed in the last 10 s before the gun.
• The jib sheet % channel read 0 all day. It worked on 10 Nov (median 51 % eased); today every sample is 0 while the jib sheet angle, lead % and sheet load all read normally. Every "Sheet (% eased)" cell for today is a fault, not a setting. Worth a check on the boat.

• 11:14:31 (17:14:31 UTC) Race Team, gun 1: 2.0 m from the line at 52.7 km/h, M1 in 21.8 s, reach 99.7 deg at 61.3 km/h
• 11:19:43 (17:19:43 UTC) Race Team, gun 2: 4.2 m over at the gun at 62.6 km/h, crossed 0.5 s early, M1 in 22.5 s
• 11:34:52 (17:34:52 UTC) Race Team, gun 3: in H2 at 14.2 km/h in 9.6 km/h of wind, 70 m back, M1 in 97 s
• 11:57:07 (17:57:07 UTC) Development, gun 4: on time but in RUA at 22.5 km/h, 194 m off M1
• 12:02:42 (18:02:42 UTC) Development, gun 5: foiling at 30.5 km/h, 17 m back and 2 s late, M1 in 29 s
• 11:14:05 (17:14:05 UTC) Race Team: the best tack of the day, 24.5 km/h through at 17.5-20, out at 58 deg, lowest hull 867 mm
• 11:11:47 (17:11:47 UTC) Race Team: the best gybe of the day, 45.5 km/h through at 17.5-20, out at 138 deg
• 11:01:14 (17:01:14 UTC) Race Team: tack off the foils, 9.3 km/h through, hull to -98 mm
• 11:54:08 (17:54:08 UTC) Development: tack out at 47 deg with a hull to 95 mm, 17.7 km/h through
• 12:03:37 (18:03:37 UTC) Development: the block's best gybe, 22.5 km/h through, out at 106 deg

Race Team foiled upwind from 12.5 km/h; Development mostly sailed H1 and H2 in the same band.

• Time in each mode, 12.5-15 km/h: Race Team foiling 53 %, H1 23 %, H2 15 %. Development foiling 13 %, H1 38 %, H2 11 %. At 10-12.5: Race Team H2 53 %, H1 17 %; Development H2 60 %, H1 9 %, foiling 6 %.
• Foiling, 12.5-15: Race Team 52.0 deg at 36.5 km/h, 23.5 km/h of VMG (10 periods). Development 56.4 deg at 35.7 (18.2, 4 periods: a pointer). NZL (Valencia, J1) 49.5 at 41.5 (29.0, 11); SUI (Valencia), the best boat, 49.9 at 41.4 (27.1, 26); NZL (Pensacola 10 Nov J2) 50.1 at 39.4 (26.0, 24). Race Team: twist 21.7 deg against 22.9-30.8, leeward cant 5.1 against 2.5-4.6 (- = more).
• Foiling, 15-17.5: Race Team 43.7 deg at 40.3 km/h (29.6, 18). NZL (Valencia Fri, J2) 40.2 at 44.8 (35.0, 14); NZL (Valencia Sat-Sun, J1) 52.1 at 39.7 (25.8, 27); SUI 53.8 at 39.4 (23.9, 13). Against the J2 reference Race Team was 3.5 deg lower and 4.5 km/h slower, with cant 4.1 against 1.9 and twist 24.2 against 30.5.
• Foiling, 17.5-20: Race Team 39.3 deg at 41.6 km/h (32.1, 8). NZL (Valencia Fri, J2) 45.0 at 46.6 (33.2, 66). 20-22.5: Race Team 38.7 at 43.6 (34.8, 4); NZL (Valencia Fri) 42.7 at 45.3 (33.3, 33). In breeze Race Team pointed 4-6 deg higher for 1.7-5.0 km/h less speed; NZL (Valencia) carried more cant (0.1-0.6 against 1.8-2.9) and more twist (30.8-31.3 against 26.8-28.6).
• H1, 12.5-15: Race Team 53.1 deg at 21.3 km/h (13.2, 7); Development 58.6 at 22.5 (12.4, 11); NZL (Valencia J1) 53.2 at 22.7 (13.6, 16); NZL (Pensacola 10 Nov J2) 48.2 at 22.6 (15.0, 9). Race Team: clew -170 mm against -423 for Development, twist 16.8 against 23.4. H1, 10-12.5: Development 55.6 deg at 19.9 km/h (11.2, 7), level with NZL (Valencia) 60.4 at 21.0 (10.7, 12) and 10 Nov 59.4 at 21.4 (11.1, 7). H1, 15-17.5: Race Team 46.0 at 20.4 (13.5, 7); SUI (Valencia) 45.4 at 19.7 (13.9, 8).
• H2, 10-12.5: Race Team 46.2 deg at 12.6 km/h (8.6, 17 periods); Development 47.4 at 13.2 (8.9, 36); NZL (Geneva) 51.3 at 14.3 (8.9, 12); NZL (Valencia J1) 53.2 at 12.9 (7.7, 24); SUI (Valencia) 41.2 at 15.2 (11.0, 13). Both crews beat NZL (Valencia) and matched NZL (Geneva); SUI was 5-6 deg higher and 2-3 km/h faster than both. Race Team's leeway 5.5 deg against 3.1-3.7 for Development and the NZL references, with more camber (32.3 against 24.1-28.9) and the clew further to windward (-469 mm).
• H2, 7.5-10: Development 48.1 deg at 11.3 km/h (7.5, 38); NZL (Geneva) 47.9 at 11.8 (7.9, 10); Race Team 50.4 at 12.7 (8.0, 4: a pointer). Geneva had more cant (2.0 against 4.2, - = more) at the same camber (28.5 against 28.2 deg). SUI (Valencia) reads 28.5 deg at 12.3 km/h here, which looks like a wind reading, not sailing. H2, 5-7.5: Development 59.1 deg at 10.3 km/h (5.7, 6).
• Ignore the NZL (Pensacola 10 Nov J2) column in the H2 12.5-15 table (35.1 deg at 12.5 km/h, 10.1 VMG, 6 periods). They are two short runs of Course work at 31-40 deg with up to 11 deg of leeway, not steady displacement sailing.
• RUA, 10-12.5: Development 46.0 deg at 15.5 km/h (10.7, 3: a pointer); SUI (Valencia) 32.2 at 15.2 (12.5, 6).

On the foils at 12.5-15 km/h Race Team beat the Valencia boats; our own 10 Nov J2 sailing was deeper and faster still. In H2 at 7.5-10 km/h Development sailed 10-13 deg higher than NZL and GBR (Valencia) and lost VMG for it; at 10-12.5 it was 8.5 deg higher than NZL (Valencia) and level with GBR. Downwind is raw and balanced between tacks, so a band sailed mostly on one tack drops out (15-17.5 foiling lost all 27 of its periods that way).

• Foiling, 12.5-15: Race Team 131.1 deg at 46.5 km/h, 30.9 km/h of VMG (8 periods). Development 128.1 at 44.9 (29.2, 4). NZL (Valencia J1) 128.5 at 44.5 (29.1, 24); GBR (Valencia), the best boat, 130.1 at 44.5 (29.2, 34); NZL (Pensacola 10 Nov J2) 135.9 at 49.1 (37.1, 10). Treat that 10 Nov column with care: two of its periods (Course work) read 41-45 km/h of VMG in 14-15 km/h of wind, which is not believable, and pull its average up.
• H2, 10-12.5: Development 130.7 deg at 14.1 km/h (9.3, 14). NZL (Valencia J1) 139.2 at 14.9 (10.8, 41); GBR (Valencia) 128.9 at 15.9 (9.8, 23); NZL (Geneva) 126.4 at 16.3 (9.8, 28). NZL (Valencia) went 8.5 deg deeper at our speed for 1.5 km/h more VMG with less camber (28.1 against 33.2 deg) and the clew nearer the middle (+557 against +1290 mm); GBR and Geneva were higher and faster.
• H2, 7.5-10: Development 124.8 deg at 11.3 km/h (6.6, 16). NZL (Valencia) 138.1 at 10.1 (7.3, 5); GBR (Valencia) 134.8 at 14.4 (9.2, 9). GBR was 10 deg deeper and 3 km/h faster with less camber (29.9 against 33.5) and less twist (6.4 against 8.6). Sail deeper in light displacement.
• What goes with speed in each crew's own foiling (fast against slow quarter): Race Team twist 22.7 against 9.7 deg and CA6 -0.2 against +15.5, at 50.7 km/h against 42.9; Development twist 15.9 against 5.1 and CA6 6.8 against 21.7, at 46.9 against 39.2 (Deep dives).

Start line to M1 only: Race Team's guns 1 and 2 gave the day's two foiling reaches.

• 80-100 deg, 15-17.5 km/h: Race Team (guns 1 and 2) sailed 99.6 deg at 61.3 km/h, 61.3 towards M1 (7 windows). GBR (Valencia), the best boat, 80.6 deg at 55.0 (54.0, 11) and NZL (Valencia) 84.3 at 39.4 (38.2, 13). Race Team 6 km/h faster than GBR, 19 deg lower.
• Guns 3, 4 and 5 didn't foil for 90 % of the reach: gun 3 reached at 17.6 km/h in 9.6 km/h of wind, gun 4 at 23.1, gun 5 at 36.2.

Few of today's turns passed the 65 % / 70 % rule, so read these as pointers against Valencia's medians.

• Tacks, foiling going in, 12.5-15: Race Team 14.4 km/h through (2), Development 17.1 (2, both touching down). NZL (Valencia J1) 18.5 (6), ESP (Valencia) 16.5 (4). Race Team came out at 70.6 deg against 54-56 for the Valencia boats.
• Tacks, foiling, 15-17.5: Race Team 19.8 km/h through (4), no touchdowns. NZL (Valencia Fri J2) 23.2 (2), GBR (Valencia Fri) 22.0 (8), NZL (Valencia J1) 18.5 (10). Race Team went in at 36.2 km/h against 45.6-47.7 on the J2 days and its lowest was 20.1 against 30.9-31.7: the speed going in is the gap.
• Tacks, foiling, 17.5-20: Race Team 22.5 km/h through (2), level with NZL (Valencia Fri) 21.7 (11) and GBR 22.1 (9).
• Gybes, foiling, 12.5-15: Race Team 23.7 km/h through (4), Development 21.0 (4); NZL (Valencia J1) 23.7 (12), AUS (Valencia) 26.1 (15). Development came out higher (99.7 deg against 118-120 for Valencia); AUS kept 34.3 km/h at its lowest against our 28-30.
• Gybes, foiling, 15-17.5: Race Team 32.9 km/h through (5), NZL (Valencia Fri) 32.8 (5), AUS (Valencia) 35.2 (6).
• Single turns: Development's tacks in H1 and foiling at 10-12.5 (one each) are video timestamps, not a level.
• Why turns drop out: a tack counts at 65 % of its crew's straight-line VMG at the same wind and a gybe at 70 %; practice turns with the app's quality score under 25 are left out. Our 10 Nov and Geneva references are straight-line only.

Five practice guns on course 26111105: guns 1-3 Race Team, 4 and 5 Development.

• Race Team, gun 1 (11:14:31): 2.0 m from the line at 52.7 km/h, foiling, at 78.6 deg; crossed 0.3 s after the gun at 55 % along; M1 in 21.8 s.
• Race Team, gun 2 (11:19:43): 4.2 m over at 62.6 km/h, crossed 0.5 s early at 93 %; M1 in 22.5 s.
• Race Team, gun 3 (11:34:52): in the lull: H2 at 14.2 km/h in 9.6 km/h of wind, 70.2 m back, crossed 16.4 s late; M1 in 97 s.
• Development, gun 4 (11:57:07): on time (0.5 m over) but in RUA at 22.5 km/h at 99 deg, at 91 % along; never crossed cleanly, 194 m off M1 at 38.9 s.
• Development, gun 5 (12:02:42): foiling at 30.5 km/h, 17.2 m back and 2.0 s late on distance, at 18 % along; M1 in 29.0 s.
• At the gun the Race Team's two foiling starts carried 52-63 km/h and reached M1 in 22 s; gun 5 carried 30.5 km/h and took 29 s, and gun 3 (in the lull) 14.2 km/h and 97 s. Gun 4 never sailed to M1: the M1 time in the table is its closest pass, 194 m away.

Roundings are timed at the closest pass of the mark in the course file and only counted within 60 m of it. Gates came 69-103 s after the foiling guns (1, 2 and 5) and 191-267 s after the others.

The day. B15 on the 27.5 m wing, LAB2 boards and LARW rudders (configuration channels 143, 4, 4), the small jib (J2) all day. Race Team 10:41-11:47 with five on board, Development Block, Jake Wing 11:47-13:00 with four. Each is its own column with its own bar.

The references (coach, 2026-11-11: "we still need more benchmarks"), all on the identical wing, boards and rudders: - NZL and the best boat at Valencia, Fri 4 Sep (J2) and Sat 5-Sun 6 Sep (J1), as columns of their own. The best boat is chosen per point of sail and per tack and gybe: SUI upwind, GBR downwind, GBR and ESP on tacks, AUS on gybes. - Our own J2 blocks of 10 Nov (Block 1 J2, Course work and Jake Wing, four on board): every period they kept in that day's report, shown as NZL (Pensacola 10 Nov J2). Straight line only. - NZL's best full-displacement periods at Geneva 18-20 Sep (J1, four on board): the SPEED v2 cheatsheet's selection held to H2, no 0.5 s sample over 200 mm on either hull, even tacks within each day. It covers H2 at 7.5-12.5 km/h.

The rules. Light day (calendar wind under 15 km/h), so the speed gates are 8 km/h. Periods are not within 10 s of a turn, have the wing set and aren't trading speed for angle, and clear 95 % of the crew's own median VMG in its point of sail, mode and band, 90 % at 12.5-15 km/h and on a tack with under half the other's periods. Figures are averages of what clears the bar, so they compare better sailing with better sailing, not how often each crew got there. Manoeuvres, starts and reaches are medians.

The crew logged three masthead wand settings: +0.7 from 10:42, -1.5 from 12:09, +1.0 from 12:42 (local).

The fitting tool came up short. It fits on foiling straight-line sailing only. On +0.7 it had 9 upwind and 6 downwind pairs, none on the other two settings, and its own check made upwind worse (port minus starboard TWA 1.6 to 6.0 deg).

On all straight sailing over 8 km/h (2-minute windows holding both tacks):

The coach's call: upwind fixed from the upwind pairs, downwind balanced. Each setting's upwind TWA was moved by half its split (+0.7: 3.0 deg; -1.5: 2.65; +1.0: +0.7's), which left +0.3 deg on +0.7 (17 pairs) and +2.2 on -1.5 (5). Downwind and AWA are as logged. A single wind rotation that centres upwind would have taken downwind from -11.5 to about -17.5 deg, the 8 Nov finding again: the error runs opposite ways up- and downwind. So downwind periods are banded on both tacks' wind (port read 0.67 km/h more than starboard, 127 pairs) and balanced between tacks, so the TWA split cancels in each average. A band sailed on one tack drops out: downwind foiling at 15-17.5 km/h lost all 27 periods that way.

The coach's focus today. Different crews (five against four), different wind (block medians 14.6 and 11.7 km/h), so only the same mode and band are compared.

Time in each mode, upwind:

Downwind both foiled at 12.5-15 (71 % and 98 %), and at 10-12.5 Development foiled more (16 % against 9 %).

Same mode, same band (TWA / boat speed / VMG, periods):

Where the set-ups differ. In H1 at 12.5-15 Race Team pointed 5.5 deg higher with the clew at -170 mm against -423, less twist (16.8 against 23.4 deg), less AWA-E1 (5.8 against 11.0) and the jib lead at 54 % against 70 %. On the foils at 12.5-15 Race Team carried more twist (21.7 against 15.4) and the lead further in (45 % against 57 %). In H2 at 10-12.5 Race Team had more camber (32.3 against 28.7) and the clew further to windward (-469 against -336), and its leeway read 5.5 deg against 3.6 for the same heel (2.6 against 2.1).

Turns. Few pass the rule. Foiling tacks at 12.5-15: Race Team 14.4 km/h through (2), Development 17.1 (2) but both of Development's touched down. Foiling gybes at 12.5-15: Race Team 23.7 (4), Development 21.0 (4).

Starts. Race Team's two foiling guns reached M1 in 22 s from 52-63 km/h at the gun; Development's gun 5 took 29 s from 30.5 km/h, and gun 4 (22.5 km/h, in RUA) never sailed to M1.

Fastest against slowest periods of each crew's own downwind foiling, wind taken out, from before the bar:

Both crews: more twist, the top of the wing flatter or inverted, more jib sheet load. Upwind, Race Team's foiling bands show the same with the wind: twist up from 21.7 to 28.6 deg and cant in from 5.1 to 1.8 between 12.5 and 22.5 km/h, as on 9 and 10 Nov. Small samples: a direction to try.

• Wind bands: 2.5 km/h, on each boat's own wind reading corrected by its calibration offset for the day. Offsets (km/h, + = the sensor reads high), from moments boats sailed within 150 m of each other: B15 +0.0.
• Bands are never merged. A band is shown only with at least 5 of our periods and 3 other boats with 5 each; for manoeuvres and roundings, 2 of ours and 3 other boats with 2 each.
• Racing is split by leg (leg 1 = reaching, the final leg left out). Practice is split by wind angle: upwind at or below 75°, downwind at or above 110°.
• Samples: 6 s straight-line periods from the app (upwind, downwind), each the mean of its ~12 half-second readings; 2 s chunks of the steady part of leg 1 (reaching: 10 s after the start to 5 s before mark 1).
• Angle words: higher = closer to the wind (a smaller TWA) and lower = further from it (a bigger TWA), upwind and downwind. Upwind, 50 deg is higher than 52 deg. Downwind, deeper = a bigger TWA, so 140 deg is deeper than 130 deg, and 130 deg is higher.
• Periods: an upwind or downwind period is left out if it starts within 10 s of one of the boat's tacks, gybes, bear-aways or mark roundings (the boat is still accelerating), if the wing is not set (under 15 deg of camber, as on a tow), or if it is trading speed for angle: boat speed falling over 1 km/h inside the 6 s while turning up upwind or bearing away downwind. What is left must be at or above 95 % of that boat's own median VMG in that point of sail, sailing mode and wind band; with teams named, each team has its own bar. The table below shows what each step removed race by race.
• Light day. Periods need at least 8 km/h of boat speed and tacks and gybes at least 8 km/h at the crossing, because the boats sailed and turned in displacement. Foiling and displacement periods are compared separately where it matters.
• Period figures are averages of what clears each boat's bar, so VMG, speed and TWA describe the same periods. They compare better sailing with better sailing, not how often a boat gets there. Manoeuvres, roundings and starts stay medians, because they are few. No figure rests on a single sample. Fleet = the median of the other boats' figures, so each boat counts once. Best boat = the other boat with the best: average VMG (km/h) upwind and downwind, VMC to mark 1 on the reach, VMG through the manoeuvre on tacks and gybes, metres below target on bear-aways, exit speed on roundings, metres at mark 1 on starts. VMG % is against each team's own polar, so it is shown for us but never used to rank boats.
• Targets: SPEED v2 cheatsheet, LAB2 27m with the Small jib and LARW rudders: the sheet's row at the band's lower wind speed (the 30 km/h row for 30-32.5), as written, never interpolated. Clew targets are converted to mm with the sign turned round (- = to windward, as in the data); jib track is converted from sheet angle to jib lead % (0 % = fully inboard). Not compared: jib sheet load (the sheet's units are not kgf yet).
• Phases included: practice, racing. Races left out: none. Crew on board: 5 for Race Team (10:41-11:47), 4 for Development. Notes: 27.5 m wing, LAB2, LARW, small jib (J2) all day. Race Team 10:41-11:47 (five on board); Development Block, Jake Wing 11:47-13:00 (four on board). Wind: upwind corrected per masthead wand setting from the upwind port/starboard pairs (config.WIND_FIX); downwind left raw, banded on both tacks' wind and balanced between tacks. As the live page: 90 % bar at 12.5-15 km/h and on a tack with under half the other's periods; a column from 3 periods or 1 turn.

• Past event days (Valencia Fri J2 2026-09-04; Valencia Sat-Sun J1 2026-09-05, 2026-09-06; Pensacola 10 Nov J2 2026-11-10; Geneva J1 SPEED v2 H2 2026-09-18, 2026-09-19, 2026-09-20): every boat follows one rule. Periods trading speed for angle are left out, then a period must be at or above 95 % of that boat's own median VMG in its band, and period figures are averages of what clears that bar. For tacks and gybes, a tack counts when it keeps at least 65 % of its crew's straight-line VMG in the same wind and point of sail, a gybe at least 70 %, the crew being a boat or one of our teams; a fixed standard, not a ranking. They stay medians. Bands are each boat's own sensor. The Deep dives tab has the detail.
• Manoeuvres are free manoeuvres only: anything within 10 s of the start, a mark or the finish belongs to the Mark roundings tab, and anything after the finish is left out. Practice tacks and gybes with an app quality score under 25 are left out (the boat was not trying); racing ones are all kept.
• VMG through the manoeuvre = ground made upwind (tacks) or downwind (gybes) over the app's 25 s window, in km/h - the measure that compares boats directly. Metres lost is the app's ghost-boat figure; each ghost holds that boat's OWN pre-manoeuvre VMG, so a boat that was quicker going in shows more loss for the same turn. For bear-aways it is distance sailed below the boat's target speed over 15 s. Touchdown = lowest hull under 100 mm.
• Reaches are start line to M1 only: the steady part, 10 s after crossing the line to 5 s before M1, straight and foiling, as 2 s samples, with medians of those. Practice sailing at reach angles is left out on purpose: on 6 Nov 2026 it was mostly turns and acceleration, with TWA moving over 3 deg inside 77 % of those periods. A reach is only compared inside one wind band and one TWA range (55-80, 80-100, 100-130 deg), both taken from the whole reach, because speed moves far more with angle than with wind.
• Tracks are GPS, and up the page is always where the wind is coming from. A turn's fixed point, T = 0, is the moment its heading passes through the turn's own mean TWD on a tack, or that + 180 on a gybe; the mean is TWD over 10 s either side of the TWA crossing, as long on each tack, so a wind sensor that reads the two tacks differently cancels. Each turn is drawn to that wind, so it points straight up at T = 0, and the app uses the same T = 0 and wind. Starts and bottom mark roundings use the average TWD of the 60 s either side of the moment, leaving out the 10 s around a turn. Every turn timing in the tables counts from T = 0 too, and a turn's line runs from 8 s before to 10 s after. Turns entered on port are mirrored. A start's line runs from 30 s before the gun to M1, and guns sharing a start line and M1 overlay on one chart. A bottom mark line runs from 7 s before the closest pass to 10 s after, the mark at the centre, on one chart for right turns and one for left, taken from the boat's heading.
• Turn time series share that fixed point as T = 0 and run from 10 s before to 10 s after, longer than the tracks so the board down button shows. VMG is the app's, made good to windward on a tack and downwind on a gybe. Yaw rate and rudder read + into the turn; clew, heel and AWA-E1 are on the exit tack's sign, so + is to leeward coming out. The old hull and board are the ones to leeward going in, the new ones to windward going in. The AoA limiter is the boat's own limit, ANGLE_DB_RAKE_LIM_deg, a rake floor already allowing for pitch. They read the report's 0.5 s data: AWA-E1 is a 1 Hz channel and clew a 2 Hz one. The button marks are the new board's down press and the old board's up press, the moment the 20 Hz board command goes on, which is ahead of the stow states the app reports. The wing invert is the app's, camber 1 passing through zero, moved onto T = 0. Each mark sits on the line at that moment. The dashed trend is a team's median at each moment, like every other manoeuvre figure, and needs two turns with a value there.
• Manoeuvre type is the commonest sailing mode from 9 to 3 s before the crossing and from 8 to 14 s after it: Full Foiling, H2, H1 to H1, Foiling to H1 and so on. Coming out starts at 8 s because the board is still raising until then. Not settled means one end was none of the modes: a hull at 200 to 400 mm, or a board still moving. The filter at the top of the tab only changes which turns are shown and counted; a single turn is never a median, so a column needs two.
