Analysis of USAP Spin Rate Test
In several previous articles, we have shown that paddle power and topspin capability go hand-in-hand (see for example, Can Topspin Enable a Faster Serve?) In an effort to limit paddle spin capability (and indirectly paddle power), the USAP established limits on the paddle face surface roughness and coefficient of (kinetic) friction (or CoF). We have […]
