That's not the way a RevFire works. It will give you speed based on the accel/decel times over the distance you set in the hand-held readout. The revolution per seconds measurement is not dependent on the ball being thrown. The spin rate can be read by just spinning the ball. When I first got mine I was playing with it trying to see how many rps I could get just spinning the ball. I was hitting 17 rps and feeling good about myself. My DD comes home from work grabs the ball without any warmups and spins the ball at 23 rps. She hadn't worked on any spin drills in years. She still had the muscle memory from all the drills she did while pitching over the years.
