Corona del Mar High School '18
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 | Rank | vs fleet rating | Record |

| 2.29 (fleet 3.71) | unranked (fewer than 30 matches as skipper, or not active) | −0.01 ± 0.18 about what the fleet rating predicts |
as skipper 15–14 (52%) |

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 (29 matches) the record is 15–14 against 18.5 wins the pre-event forecasts expected (−3.5). 0 regattas clearly above the rating (P ≤ 20%), 1 clearly below (P ≥ 80%); 3 bits of surprise in all.
