> Examples of separation/pitch/contact speed.
R=coefficient: P=pitch speed: I=Barrel speed at impact speed: S=barrel speed at separation: B=Ball speed at separation.
B=S+(R*P)+(R*I) {Note: B equals 100% of S and 40% of P and 40% of I}

S R P I = B {NOTE: S, P, I ARE IN MPH}
20 40% 30 50 52
25 40% 30 50 57 {NOTE: 5 MPH OF S = 5 MPH OF B}
20 40% 30 55 54 {NOTE: 5 MPH OF I = 2 MPH OF B}

Tthe faster the pitch the more the pitcher helps the same as impact bat speed, but the more the impact force and the slower the separation speed
