How the rope handling powers the stroke is IMO one of the most misunderstood topics of TGM.

The only way you can create clubhead speed is to pull from ahead or push from behind. The physics involved is very simple.
If you want to create speed by pulling - on a linear path, you'd better run fast If you do it on a circular path, you need to pull from something that rotates and stays ahead on the curve. Like turning left shoulder. Or the turning hands, kept out in orbit and ahead of the clubhead by extencior action. Luckily, that's what happens when you do the rope handling thing.
Anything you do to speed up the club can be decomposed as pulling and pushing (and torquing if you wish). Newton is very clear on this point: In order to do any work (and work here is create clubhead speed) you have to apply forces with the same direction as the motion. Pulling a rope from a swing center (centripetal acceleration) doesn't increase or reduce swing speed no matter how heavy it feels. It only conserves. Pulling from a point that is leading ahead on the curve and torqed around the swing center conservs and increases at the same time.
As long as the left shoulder stays ahead of the hands, and the hands stays ahead of the clubhead in the turn, any pulling will add speed. If you try to push on a straight line you will run out of arms in no time. Hitting and swinging are both depending on a turning pivot that leads the hands through impact.
