Short write-ups of what the ratings and results show, with the numbers and how they were computed.

How do skipper ratings work?A log-strength fitted to every race at once, smoothed week to week.
What a rating point is worthA one-point edge is a 73% chance to beat another boat in a race; two points is 88%.
How does a crew rating work?A crew rating is small and uncertain; a worked example on one roster.
Play 1, Play 2, Play 4: how team races are wonHow often each play happens, how that shifts with breeze and level, and whether a star wins differently.
