The difference between Hitting and Swinging putts, chips to my mind lies in whether or not you are "actively" extending your right arm.

Swinging putting uses the right shoulder (for TGM practitioners anyways) the shoulders for other, to power the putt. Zone 1.

Hitting putting typically, ideally, zeros out the Zone 1, shoulder participation and relies instead on Zone 2, active right arm extension. Arnie and the golfers of yesteryear employed Zone 3 putting. A pure hands only stroke.

So one source of power for such short shots and no need to accelerate longitudinally as the club doesnt get that far back. Its a pure Hinge Action stroke, no cocking , no swivel. Basic as opposed to Total Motion or Acquired even.

Hmm? not bad. Great approach to the question. That's the answer. Why couldn't we all see it that way?
