1) Can someone PM me innercity's address?
2) Whip - The section you quoted regarding Angular speed - that's RPM's - not clubhead speed. So Homer's contention is that the RPM's of the lever assembly stays constant upon release for the swinger and slowed slightly for the hitter based on measurements he made from photos in The Search for the Perfect Swing however realize the clubhead is picking up significant speed during release - due to lever extension etc. No book but I think the Release Section is the period of clubhead acceleration. Anyway a common mis-read that continues to confuse.
Correct he says that the centrifugal acceleration reaches maximum speed shortly after release and tries to remain constant, this is separate from clubhead speed which per the endless belt picks up speed significantly as the lever is extended going around the pulley.

Reason: correction
once the left wrist is uncocked the lever is at full extension and the clubhead speed will be proportional to the angular speed of the center and the velocity produced by the size of the pulley. Most players with the exception of David toms only uncock to level from the period of swivel hinge and impact and terefore once the maximum speed is created by the lever extension it will remain constant so long as you keep turning
I was able to see that you understood and agreed with my post however I was not sure I was able to exactly comprehend your entire post. If I were to summarize an area I don't think you had quite right then I would say that you were saying - Once the swinger's left wrist uncocks to a level position the clubhead no longer picks up speed.
That would only be true for a zero number three accumulator. The release in reference to the endless belt refers to number two and number three accumulators, once the left wrist uncocks to level then the roll of the number three accumulator adds significant clubhead speed for the swinger, that's why you have it in shots where you want additional power.

Is the point of the "endless belt" that it always moves at a constant rate of speed? I wouldn't think HK would violate the physics of the planet in that way though it is a good analogy for everything else.

when the hands move around the pulley portion of the endless belt the clubheads speed will pick up considerably as it flies out around the pulley extending the lever length. in other words during release the hands move a short distance and yet the clubhead will move some 3 feet or so at the same time. we need not speed up the hands during release to get clubhead speed, constant hand speed is a tgm virtue

When snap releasing, the hands slow precipitously in the release interval. They also slow in a sweep release, but not as dramatically. Constant hand speed exists only in the endless belt model.

Agreed constant hand speed is assumed in the endless belt analogy for illustrative purposes only. Actual constant hand speed when swinging would imply no rate of acceleration therefor no Lag Pressure wouldn't it? Something a few GSED's got wrong maybe? You don't want to swing the hands at a constant speed......and how could you do that anyways? Slow and steady acceleration may feel like a constant hands speed however...
I must remind myself, any time I think about trigger delay and snap release, to use care of Right Arm Geometry. The limits are set by ability to maintain the Right Flying Wedge all the way to impact. There is a trap that is seen too often. The right forearm must be thrown, slap, into impact and not allow the sholder, elbow, hands to stall and have, what I call, a FAUX pp#3 by unbending the right wrist to hold #3 pressure by "flipping"
it against the shaft. There are also right arm participation limitations to "snap relase".
just my own thinking

Of course, I didn't invent any of this:
For an articulate view:
One more comment:
I do not feel the right wrist "froze" in place by any effort of the right wrist, but, held in place by the alignments of the right forearm, elbow, shoulder, axis tilt and pivot. ie. the right wrist alignment is a result.

what??? of course there would be lag pressure ob, they didnt get it wrong. YOU DO WANT TO SWING THE HANDS AT A CONSTANT SPEED, you move them at the same speed, you are not speeding up down there, constant hand speed is not hard at all, why are you guys saying constant hand speed is not possible???

according to what information do you make this statement?

That's the point, because of the physics, you can't.
