The answer to your question about how the pitch speed effects ball exit speed from the bat is answered in a study that Paul pointed to.
> It's at www.nisss.org/BBSPEED6a.html
> Figure 16 shows that ball exit speed from the bat only goes up a little as pitch speed increases. But it turns out that Figure 17 explains even this small increase in ball exit speed. It's because the bat speed is increasing as pitch speed increases. We swing faster at pitches that make us get there quicker and swing slower as the ball goes slower. Pitch velocity has little to know effect on how hard a ball is hit.>

>missouri dad....it's been a long time since i have seen any of your posts...where have you been?....i always enjoyed reading your posts.....however, on the issue of "Pitch velocity has little to know effect on how hard a ball is hit.", i have to ask you: can you picture mark mcgwire hitting a ball off a tee (zero pitch speed) 500 feet?....somehow i don't think he could....respectfully, grc....
