should the reading off a revfire be the same when spinning the ball stationary (ie. no arm circle just wrist/finger spin) vs in a full pitch or should the full pitch have a higher reading?
The spin reading should be measuring the rotation (RPM) of the ball, regardless of the arm motion.
It's RPS, Revolutions Per Second. It reads the RPS when stationary. When mine arrived I was playing with it. Got it up to 17 RPS on a riseball spin. DD happened to come home from work at the time. She wanted to give it a try. Ice cold and not having done any riseball spins in years she grabs the ball and hits 23 on the very first spin. Yup... Hung my head in shame..

Yes, as expected I typically see a slightly higher reading from someone throwing full motion.
23! i could hardly hit 15 with a RB spin. can you ask your DD, what's the secret to getting 23?
Doing literally close to a million of them from the time she was 12 till she finished college. She used to watch TV or walk around the house spinning the ball over and over. Couple that with untold thousands of football drills. Used to keep it in the car so if we were some place and had 15 minutes she would work it.
She had a great riseball. It was her strikeout pitch. When she was pitching in college and doing her spins the seams were a blur when she spun the ball.
Sparky,
I will let DD read this and read it again and again. '
thanks!
