Agree that it could be read like that - throw at the Top. However, that is not what he is saying. And you are not "throwing" anything in regards to your effort. Look at it this way - if you are throwing a ball to a catcher - you create momentum in the ball and once you send it, it has it's own momentum until it hits the catchers glove. The swinging concept in regards to "throw" in this lag loading context - means that you create independent momentum in the golf club - say a lagging takeaway or backswing - and as your hands slow down somewhere on the way back before the Top - the club has it's own momentum and continues on - i.e. is thrown (not in the true sense like the baseball but indirectly thrown) where it hits the "catcher's glove" or the #3 pressure point and potentially creating pressure among other pressure points.
This is opposed to the Hitting loading procedure where the left arm and club work as one unit - the #3 pressure point with the right arm and the supporting body slows down the backward movement of that whole unit as it approaches the TOP, that resistant to that backward motion loads the #3 pressure point and maybe others.
You "swing" back the clubshaft in swinging and "carry" it back in Hitting.
Realize that secton like most in the book just describes the basic nature of the two procedures - it's like drawing a few lines for a "stick man" and saying "that's a human being", there is certainly a lot more to it than that. One might want to exaggerate the feel at the beginning in order to accomplish it, however ultimately you might see someone setting their wristcock very early and they could be swinging. Ultimately the procedure,feel, focus can be subtle and simple - as opposed to what one might mis-understand, mis-apply or initially need to feel in order to achieve the desired result in regards to terms like "throw". So early on would a soft grip allow you to sense, create or exaggerate the correct loading - absolutely - however once understood and applied it you could do this with a firm grip.
So eventually this "throw" would be as subtle as a release "throw" - you'd be unaware of when you did it, where you did it - when you're on the golf course executing - it just "would be". Ultimately it's just another "mechanical" feature of the movement, not something that always has your total focus.
really good post....you back on the pipe obvously....
