>>> If 98 degrees of shoulder rotation produces 250 degrees of bat rotation, then is there basically a multiplier effect where a very slight difference in body position, rotation, etc., produces a much larger difference in the resulting swing - especially early batspeed, etc? <<<

Hi Chuck

Yes, I would say there is a multiplier effect. You could think of it as a catalyst where a small amount of energy applied during initiation can make a large difference in the contact zone. This is also supported by the bio-mechanical principle that states: “I ballistic motion, once initiated, produces trajectories that can be changed only at its’ margins.”

As and example; A small amount of rearward force applied by the top-hand during the initiation of the swing, results in much greater bat speed at contact.
