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

Agreed - absolutely!

As a side note - since Homer makes the distinction - I'd be very clear when you write it for others sake- that is what you mean by "club". The clubhead picks up MPH during release and the clubshaft maintains it's RPM's during release. For what it's worth.

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...

Right arm participation
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
hb

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?

With more time , tonight maybe , I can support my position with book reference. But for instance period of shoulder acceleration , period of arm acceleration etc.... how can these things be speeding up if the hands are not? Lag pressure is a product of the rate of acceleration of the hands. Now to do that without the rate dropping off, to sustain lag pressure in other words you have to start down slow and build it up at a steady rate. No over acceleration to a rate that can't be maintained. In so doing it may feel very slow in terms of build up of hand speed. Thinking its a constant speed , though false , may help you in this effort. In other words its feels constant but it isn't.

once the machine reaches the period of release (clubhead acceleration) the hands do not need to be speeding up around the pulley nor do they have to slow down, constant handspeed. what is your alternative? speed up, slow down, during release? Good luck with focusing on the alternatives. Constant handspeed allows the structure, the mass of our extensor action, our wrists, centrifugal force, and rhythm of all zones working in harmony to produce power and accuracy that is literally effortless

Ok I'll strap a speedometer to my hand and take some golf swings, I'm betting i can keep a constant hand speed throughout the release.
