What is pushing these ratings up or down

Crews are only compared through the skippers they have shared. A skipper's boats do a little better or worse than their rating predicts depending on who is crewing, and the rating is built from those differences. Each big blue dot is a crew on this roster, each small square a skipper they have sailed with, and each line a pairing: blue pushes the crew up, orange pushes them down, thicker means more racing behind it. Click a crew or a skipper.

Ranked crews have at least 8 races this season; * means low evidence (under 8 races this season, or under 30 career races with rated skippers). Ratings are on the skipper scale (×18.7 the crew effect). League percentile also reflects how strong the team's skippers are.
