IMO, there's 2 parts to Endless Belt Effect.

1. The hand speed in the downswing should remain at a constant rate. I'll make up some numbers, but if the hands are moving at 50 mph at impact, then they should be moving at 50 mph in the start down. Constant rate of speed. You don't want a jerky hand movement.

As the hand speed is constant, the clubhead speed up. So if the clubhead speed is 100 mph at impact, then it could be at 75 mph in the startdown then say 90 mph at the halfway down point...accelerating into impact.

Again, the numbers that I'm using are made up, but trying to illustrate the point.

2. The size of a golfer's 'pulley' plays a factor in *how* they generate clubhead speed.

A smaller pulley is something more along the lines of a 'snap release.' A larger pulley is something more along the lines of a 'full sweep release.'

Johnny Miller had more of a full sweep release and Lee Trevino had more of a snap release. The same with straight line delivery (small pulley) vs. circular delivery path (large pulley).

Let's say that both guys had a driver clubhead speed of 110 mph. Since Miller has a larger pulley than Trevino, that means that Miller must have faster hand speed than Trevino to obtain the same clubhead speed.

I have a Random Sweep release. If I want to increase clubhead speed, I would either have to make my pulley smaller (more of a snap release) or just increase my hand speed with the same Random Sweep Release.
