Halfway through I forgot about another variable and that is RP to FF. In order to simplify this I combined stride length and RP to FF. (the ML average RP to FF is 0)

Here I present you with a table:

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…

I thought this was an interesting topic so I made an Excel spreadsheet to see where the numbers came at. Although the numbers don’t seem to match what I’ve seen quoted, none have shown their formulas. But if you look at the 100% stride and 0% stride in my chart, you see that the 0% stride matches with the release velocity. This leads me to think that most quotes on this subject are talking more about the change in stride percentage as opposed to the overall effect of stride as shown in my chart.

One of the things that stands out is that the effective velocity based on stride is effected greatly by the pitcher’s release velocity. At the higher end of the release speeds you see about 1mph per 10% stride increase, but at lower release speeds you see about 0.8mph per 10% stride increase.

To simplify things, the release point is calculated at the point of front foot strike. So you can adjust +/- depending upon the pitcher’s height and stride to get an idea of other release points.

Also when I change the pitcher’s height from 6′ 2″ to 6′ 4″ , I see about 0.4mph increase in effective velocity at higher release speeds at 100% stride, and 0.2mph increase at 60% stride. But lowering the pitcher’s height to 6′ 0″, the difference is about 0.4mph for most release speeds and stride percentage.

Please feel free to let me know if you think the calculations have an error, and why. As I said, the numbers don’t match what I see quoted, but the formulas I used seem sound to me. The forum only lets me upload a PNG, so I couldn’t upload the Excel file.
