I've done 10 of the 12 pitches now.

Variables are defined

IR : Internal Rating for pitch
GB : Groundball %
M : Movement Rating
V : Velocity (1-20)

All the following give a value on the 1-200 scale (obviously it can go over 200, so these would be > MAX on chosen scale)

Fastball : (V*6)+(IR*0.4)+1
Sinker : (V*3)+(IR*0.3)+(GB*0.6)+(M/6)-(13/6) subject to a minimum of 6
Knuckleball : IR + 1
Knucklecurve : (IR*0.8)+(V*2)+1.6
Screwball : (IR*0.8)+(V*2)+1.6
Circle Change : IR + 1
Forkball : (V*4)+(IR*0.4)+(GB*0.3)+(M/12)-0.3 subject to a minimum of 6
Splitter : (V*4)+(IR*0.4)+(GB*0.3)+(M/12)-0.3 subject to a minimum of 6
Changeup : IR + 1
Cutter : (V*4)+(IR*0.4)+(GB*0.3)+(M/12)-0.3 subject to a minimum of 6
