Sure Steve;
A given is the old F=MA (Force = Mass X Acceleration) Thus, my statement inferes that there should be acceleration through - not to contact. The formual is not Force = Mass X Velocity. So even if the maximum velocity was reached prior to contact - maintained at contact - and consistant after contact - physics tell us that a greater force will be exerted through the use of acceleration.

EXAMPLE: where the contact bat speed is X and equal in both 1 & 2

1. Start swing (X-50), acceleration to (X), contact (X), post contact (X), deceleration (X-30) - (X-50)end swing

2. Start swing (X-50), acceleration to (X), contact (X), post contact (X+5), deceleration (X-30) - (X-50) end swing.

Because of the acceleration through the contact point a greater force is delivered even with the same impact velocity as represented by (X).

Hope this helps
