Reply to "Spin rate"

Root,

What about the rate of deceleration?  Any data in regards to time of flight compared to max velo and spin rate?

If it takes a 85mph 4 seam with a 2200 rpm .45 sec to travel 55ft.  How long does it take at 2500 rpm?  

 

My guess would be that, because it drops slightly less and takes a slightly straighter path to the plate (perhaps the total flight distance of the pitch is as much as an inch shorter because of less "curve" in the actual flight pattern), it would get there slightly sooner. Since deceleration occurs at a non-linear rate, my guess is that that last inch could make the same pitch arrive at the plate as much as 1-2 mph slower. I'm sure the math could be done, but it's beyond my abilities. I'm a lawyer. I was promised there's be no math in my profession.
