>>> In the stable athlete who reaches say a bat speed of 75 mph (just a round number) and has achieved an ideal summation of those velocities (Ideal Kinematic Sequence), the ball exit speed will be equal to or greater than the bat speed. Meanwhile, in the frame immediately after contact, our research has found that the bat in the most efficient swing will lose from 0 to 5 mph in bat speed. (Ideal of course is zero, but we have never found anyone (all of today's greats included) who loses less than 3 mph on the next frame

The athlete's swing with less than ideal summation of those velocities, (Poor Kinematic Sequence), the hitter's bat reached its maximum velocities (rotational and linear) and within 1/240th of a second lost as much as 43% of bat speed immediately after impact. <<<

Hi Zig

If I am interpreting your statements correctly, a batter who attains a 75 mph bat speed at contact with Ideal Kinematic Sequence could expect a 0 to 5 mph loss of bat speed during contact with the ball. Whereas a batter with Poor Kinematic Sequence may attain the same 75 mph bat speed, but could lose as much as 43% of that speed during contact.

Is that is a fair assessment of your statement? I am not making a judgment, just seeking clarity.
