do you know what the average differential in velocity is in MLB for pitchers (difference between peak velocity at time of release and plate speed)? How about for 13-year olds?
I have read, but I don't remember where, that there is about 4-5 mph difference from the point of release of the baseball and the speed of the ball as it reaches the plate. Basically, if a 13u pitcher has a release velocity of 75 MPH, the velocity may be 70-71 when it reaches the plate.

The consensus I've seen online and in the radar instructions I have is that you lose about 1 mph per 7' from release. So if you're releasing at 95, you'll be at 86-87 at the plate on a full size field.

Anecdotally based on a few readings I've gotten on some AA pitchers, I think the rate of loss is lower at the youth level, more in the neighborhood of 1 mph per 10' at a 50-60 mph release speed, which would agree with what you've read. I know that the power necessary to overcome drag in a car increases proportional to the cube of the velocity, so it makes sense that the drag on a faster pitch would be higher.
