What the wind changes.
What the numbers measure.
A local wind estimate and a consistent VMG calculation, with the uncertainty left visible.
Whole-leg results include routes and turns; steady VMG counts only straight-line sailing beside other boats on the same leg, each race weighted equally.
All races start included. Comparisons without sufficient evidence remain blank.
One measure, consistent aggregation
Matched steady sailing · local wind direction
100 is the reference and above 100 is better VMG. The reference is nearby boats sailing steadily on the same leg at the same moment.

±5° direction sensitivity: 102.9–104.2. This is not a confidence interval.
Speed and direction, reconciled with VMG
Right is faster; up converts more of that speed into progress along the chosen direction. The curves are equal-VMG indices, calculated exactly from these two factors. Direction efficiency is a projection ratio, not a measured pointing angle.
The race-by-race check
Same selected measure, same race cells. A blank means there is no qualifying result, not zero performance. Other boats may cover fewer races; compare their coverage before ranking them.

Does the answer depend on the wind neighborhood?
For WAH GWAN, this rebuilds the wind fit with its spatial and temporal support 25% narrower or wider. Peer distance stays at 600 metres. These choices can change which samples qualify, so the matched minutes are shown too. A large change is a reason to treat the result cautiously.
