>>> OK Jack, Tell me why EVERY ONE of the big leaguers on the RVP disc that are pulling the ball have the bathead ahead of the hands at contact. They are the best hitters in the world filmed hitting balls into the seats. The camera angle is excellent. <<<

Hi Doug

I stated earlier, “On pulled balls, the top-hand (and bat-head) may have passed the bottom-hand in relationship to the path of the incoming ball. However, in relationship to the direction the hands are arcing, they are comparatively (give or take a couple degrees) in-line.”

Obviously some people with an RVP disc are just not comfortable with “in relationship to”, therefore I will try again using “in reference to.” --- “On pulled balls, the top-hand (and bat-head) may have passed the bottom-hand ‘in reference to’ the path of the incoming ball. However, ‘in reference to’ the direction the hands are arcing, they are comparatively (give or take a couple degrees) in-line.”

Note: I think what mb is referring to is that a bat tends to stay tangent with the direction of radial force (CHP). Once the bat swings past tangent, the n-factor tends to decelerate it back to tangent. This is why the “hook” in the hand-path (increased rate of angular displacement) is so important in generating bat speed.
