Spin Rate Factor (SRF) using the DigiBall

Polishing up some app features…

Spin Rate Factor (SRF) is the ratio of ball revolutions to the number of ball circumferences traveled. A perfectly rolling ball will rotate exactly once per circumference traveled, and is 1.0 / 1.0 which is 1.0. SRF is a useful parameter to measure the spin quality of a shot independent of shot speed. In this video I show how draw shot action can vary in quality.

Wouldn't that be SRF? I mean unless you're playing out in the sun...
