Places per race a team should expect to gain or lose in this boat against what its sailors' ratings predict, from a model of this fleet fitted on every regatta sailed here since Spring 2023 (1 regattas). Shown at the 40% that holds up on regattas the model never saw; hover a sail for its value and uncertainty. Grey = boat not in the fit. How this is estimated.

Orderliness — underdogs or favourites?

Breeze: S 9 kn (scorer’s report)
In this breeze at Columbia YC: a favourites’ day (+0.02)
Back the top seeds: results should follow the ratings, and the gaps between favourites hold.
Fleet adjustment +0.09 (a softer or greener fleet makes the ratings stick) · combined forecast +0.11
Actual: about typical, within noise (+0.17 ± 0.23)

Orderliness is how tightly the finishing order followed the pre-regatta ratings, relative to a typical event (0). Positive is the favourites’ day: the ratings carried more weight than usual and the top seeds finished where expected. Negative is the underdogs’ day: the fleet compressed and the favourites came back to the pack. A value of ±0.02 means a rating gap counts about 2% more than on a typical day.

The breeze reading is the chart’s value at this regatta’s wind direction and speed (the star): this venue’s pattern of which directions bring order and which bring upsets, with breeze generally orderly and light air surprising. The fleet adjustment comes from the entry list: the stronger and more experienced the fleet, the more surprising the racing. How this is estimated · compare venues.

Orderliness beyond the fleet at Columbia YC by wind direction (angle) and speed (rings), fitted surface; dots are labelled regatta-days, ★ this regatta (only 1 labelled days at Columbia YC, so the surface is mostly the all-venue pattern).
