University of Wisconsin Milwaukee '15
How much better or worse boats do with this sailor crewing than their skipper's rating predicts, shown on the skipper scale so crews can be lined up across teams. Percentiles compare against rostered crews that season (league) or teammates (team).
How crew ratings work →Crew effect over their whole career, not scaled to a team: 34.74 percentile among ICSA crews with 30+ races. Uncertainty ±0.117 rating points from 12 races with rated skippers. Few races, so the estimate stays near the middle.
How crew ratings work →No season rating yet: needs 8+ crewed races in a season.
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.

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 2 graded regattas (15 matches) the record is 4–11 against 3.0 wins the pre-event forecasts expected (+1.0). 1 regatta clearly above the rating (P ≤ 20%), 1 clearly below (P ≥ 80%); 2 bits of surprise in all.
