Pre-event forecast

Fitted on the 11,868 team race matches sailed before 2025-04-06, using the line-ups that actually raced. It called 45 of 45 matches (100%) with a log-loss of 0.169 (a coin flip scores 0.693), so the event went well for the forecast. Orderliness +0.69 ± 0.34: an orderly event, more orderly than 91% of high school team race events (temperature of the forecast log-odds that best fits the results, relative to the league average; nothing about the field, venue or wind predicts it, see the Weather tab). vs forecast is a team's wins minus the wins the model expected from the matches it sailed: positive means it beat its rating.

Surprisal: who beat their rating

Pre-event strength against the strength that would have made each record least surprising, everything else fixed. Δ is in the model's logit units, the same scale as the boat values above (a side is three boats plus the school term); green is a clear over-performance, red a clear under-performance. Skippers need three or more matches.

What this breeze does at Severn — from fleet racing

Breeze: N about 9 kn (weather reanalysis in the scorer’s units)
In fleet races at Severn in this breeze: a strongly underdogs’ day (−0.14)
Underdogs’ conditions: in fleet racing here the fleet bunches up and lower-rated boats beat the seeds more often than usual.

Orderliness is how tightly a fleet race’s finishing order follows the pre-regatta ratings, relative to a typical event (0): positive is the favourites’ day, negative the underdogs’. A value of ±0.14 means a rating gap counts about 12% less than on a typical day. This event is not a fleet race the rating model scores, so there is no actual value for it: this is what this venue’s fleet racing history says about the breeze on the day, read off the chart at the star. How this is estimated · compare venues.

Orderliness beyond the fleet at Severn by wind direction (angle) and speed (rings), fitted surface; dots are labelled regatta-days, ★ this regatta (only 4 labelled days at Severn, so the surface is mostly the all-venue pattern).
