Skipper ratings over their careers
Week at Junipero Serra High SchoolWeek before / elsewhereLine colour = skipper (’yy = graduating class)

Weekly rating of every skipper on the roster across their whole career so far, one point per week their rating moved. By class year lines every graduating class up at the start of its freshman year, so each class sits one year further left than the one after it. Hover a line to isolate it.

This team had fewer than 3 crews with 8 or more races, so crews are listed, not ranked, and rated against the average of the crews listed. 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.
