A 65-degree play is far from a 30-degree play and a 50-degree play. Like 50-degree play, the angle is adjusted with the wind, and the angle influence of downwind+headwind-is twice that of wind. For example, if the distance is 20 and the downwind is 2.5, then the angle should be 70, while the headwind is 2.5 and the angle is 60.

Basic formula: 65-+ (wind times 2)= angle (forward+backward-)?

Strength according to the above table, the corresponding distance versus stress.
