So DD had her first camp where they measured bat speed. It was measured via a device tracking the bat.
I now have a Pocket Radar. The Pocket Radar folks say measure bat speed via the ball hit off the tee.
Question is this : what is the better figure "Bat Speed" or "Speed of the ball off the bat"?...
I think it's the latter given that bat speed is going to be different off end-loaded bats vs balanced bats.
