2nd bolded - No it won't remain constant in the real world - too much friction in the human machine - remember the word "tries"?

3rd bolded - You are carrying the pulley analogy too far. In the golf swing, the pulley section is less than 90 degs, not 180, and the hand speed isn't constant as it is in the endless belt pulley.

4th bolded - I brought it up. If you over accelerate the hands from the top and sweep release, you will have to steer to get the hands to beat the club head to the ball.

5th bolded - And if my Aunt had testicles, she would be my Uncle, which would also be a completely separate factor.

6th bolded - You can't push a shopping cart any faster than you can run, no matter how hard you try.
Mike O would like to get your aunt's phone number......

Another brilliant geometric golf set of insights!

Two points
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.

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.

Not really, most of the power comes from the uncocking left wrist, while throwout is principally the delivery mechanism. It's primary power function is to sustain compression in the impact interval and maximize separation velocity. Also, you have throwout in all shots, not just those which require additional power.

sorry if my post was confusing, i hadn't factored in the #3, you are right that angle is a power source of its own and when transferred by the #2 supplies considerable power.

Once the club is released it IS NOT slowing down by any means, so the idea that we must delay the thing long enough so we don't have time to lose speed is not correct. make no mistake the club must be released sufficiently in time to uncock, roll and hinge. Homer has no sympathy for anyone who overemphasizes any one thing or another. with tgmers it tends to be forward lean, and trigger delay, you can't just skip the hinge motion, the hinge is one of the key elements to controlling the golf ball.
