>>> Jack, I can understand why you want to ban the term "scap load", considering all of the insults outsiders have made, promoting other web sites, etc. But if you could just bear with me, I would, if I could, once and for all, get a brief analysis from someone who is familiar with both terms as to what, if any difference there is.

I read what Paul made available at Setpro. What struck me first was that although he described most of the muscles and bones involved in “scap loading,” he never described what effect the mechanic had on the bat’s trajectories.

However, if “scap loading” (and the pulling back of the elbow – and thus, the top-hand) is claimed to accelerate the bat back into the swing plane, then we have a problem of someone claiming a defined batting principle by giving it a different name.

> From my research, the defining mechanical principle that separated the great hitters from all the rest, was that they first accelerated the bat-head in an arc back toward the catcher with a mechanic I termed “Top-Hand-Torque” (pulling the top-hand back). I think you will find that many average hitters “load the scap” while preparing their launch position. But these hitters do not accelerate the bat-head back into the swing plane (THT).

Once the bat is in the launch position, average hitters do not accelerate the bat-head back by pulling back with the top-hand. They thrust their top-hand forward.

jack....you said "average batters may start with a more vertical bat, but they bring their bat to a near stop (little or no angular displacement) at the launch position before they initiate their swings. Once the bat is in the launch position, average hitters do not accelerate the bat-head back by pulling back with the top-hand. They thrust their top-hand forward."......

i believe you are correct...i don't want to beat a dead horse but i think this is consistent with my "bat cock thing"....if the bat (at start of stride) is vertical & no cocking taking place, by launch position the hands (and knob) will be in no position to go anywhere except, as you point out, forward...thus, no chp but instead linear...furthermore, there is no "torque position" (i use epstein's term as a matter of convenience to describe the hips being rotated 15-30 degrees by heel plant)....and, of course, more of a tendency to contact at full x-t, rather than the more desirable "L" in the top arm...and of course, this in turn resulting in less hip rotation (and consequently less shoulder rotation)....
