Every analyzed session, newest first, from every location — each card is labelled with where it happened. Each one is a GPS track joined second by second to the measured local wind, so the angles and the transition classifications are against a real reading rather than a forecast.

The same true-wind-angle bins for every board · wing · front wing combination, so they can be read against each other. The count under each name is how many sessions and how many foiling seconds are behind that line — one session is one afternoon's conditions, not a settled polar.

Success rate and average speed loss per session, in date order. Both are 5.1's own numbers — a transition counts as a success when the speed never drops below its minimum, and the loss is the drop from entry speed to the dip.

That session id is not in the index.
