Distance correlation to velocity chart

does anyone know of an accurate chart which could tell a player how fast there throwing in MPH in correlation with their throwing distance?

Velocity = Displacement (Distance) divided by Time. (V = D / T) You’d have to nearly exactly meausure the distance and the time, and the ball would have to be thrown as straight as possible. If it veers off, you have to measure it a certain way to get it back to the line.

Basically, you’re much better off getting a radar gun.

… but knowing the velocity of a ball thrown with long toss mechanics and trajectory won’t tell you what your velo will be on a mound, under different conditions.

long toss doesnt matter
i know someone who can hit low 90’s but he cant throw long toss if his life depended on it
