[whip]

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

Constant hand speed exists only in the endless belt model.

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.
