Performance rating asks, for each skipper: holding every other boat fixed, which rating makes my actual race-by-race finishes least surprising? Boats are valued with the keelboat rating rather than the fleet rating: 0.41 × the skipper's fleet rating from the week before the event (unrated skippers start at 0.47); 0.28 × the mean fleet rating of the rated crew aboard; the skipper's own keelboat offset; the school's program effect. Non-finishes (OCS, DNF and similar) are left out of the fitting, as in the rating model.

Percentile places a rating among the 78 ISSA sailors with a keelboat rating who raced the discipline in the last three seasons. Surprise is how many bits more surprising the finishes were at the pre-event rating than at the performance rating. P(this good or better) simulates the event 3,000 times at the pre-event ratings, with the same regatta-form model as the fleet analysis pages, and reports how often the skipper would score this many points or fewer in the races they sailed.

The keelboat offsets are the current ones (the discipline files keep no weekly history), so a skipper's own offset has already seen this event; offsets are shrunk hard, so the effect is a few hundredths at most. Only skippers are rated.

What this breeze does at DePaul College Prep/Latin of Chicago/New Trier HS/St. Ignatius (IL)/Walter Payton Colleg — from fleet racing

Breeze: W about 7 kn (weather reanalysis in the scorer’s units)
In fleet races at DePaul College Prep/Latin of Chicago/New Trier HS/St. Ignatius (IL)/Walter Payton Colleg in this breeze: an underdogs’ day (−0.02)
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 ±0.02 means a rating gap counts about 2% 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 DePaul College Prep/Latin of Chicago/New Trier HS/St. Ignatius (IL)/Walter Payton Colleg by wind direction (angle) and speed (rings), fitted surface; dots are labelled regatta-days, ★ this regatta (only 1 labelled days at DePaul College Prep/Latin of Chicago/New Trier HS/St. Ignatius (IL)/Walter Payton Colleg, so the surface is mostly the all-venue pattern).
