West Sound Academy '24
A team race rating is what the sailor brings to one of the three boats: 0.72 x their fleet rating plus a team-race offset learned from every match they sailed, shrunk toward zero so a few matches cannot move it far. Sides are compared by the sum of their three boats plus the school's team race strength.

Rating before each regatta driven (solid; dots green when the boat won 60% or more of its matches there, red under 40%) and what the fleet rating alone would give (dashed). The gap is the team race offset as it stood at the time. Hover a dot for the regatta; click to open it.
For each regatta, the boat value that would have made this sailor's record least surprising: the shift applied to their boat alone, in the matches they sailed, with team-mates and opponents fixed at the pre-event forecast. A boat's skipper and crew share the boat, so they get the same number when they sailed every match together. Surprise is in bits at the pre-event value minus at the performance value; P(this good or better) treats the matches as independent at the forecast probabilities. Regattas forecast from fewer than 1,000 training matches are left out.
Over 3 graded regattas (32 matches) the record is 17–15 against 19.7 wins the pre-event forecasts expected (−2.7). 1 regatta clearly above the rating (P ≤ 20%), 2 clearly below (P ≥ 80%); 5 bits of surprise in all.
