I will post a file that you can open up to see the graphs.
I notice a few interesting things. 1st is Billy Wagner's insane amount of Visual Velo. The main component to this is that his RP to FF is a full 12 inches. That in itself is 3 mph! 2nd I see Stephen Strasburg's negative amount of Visual Velo. He is actually working against himself with such a short stride! I wonder if he were to lengthen that stride, if he would also through harder…
The release point is another way the pitcher can affect velocity. The closer to the plate the ball is released the greater the perceived velocity. The estimate is that for each 1 foot closer to the plate there is an approximate increase of 3 mph.
An additional interesting concept is "Effective Velocity" - the initial velocity plus the location effects of the pitch due to different locations having different reaction times for the batter.
