Real-world polar and manoeuvre analysis from the instruments already aboard.
Only angle buckets with at least three readings are plotted. Sparse areas fill in naturally as more sessions are recorded.

A tack is counted when the wind side changes during an upwind leg within 120 seconds. Recovery is time back to 90% of entry speed.
