I would call my "Putting" with EA dynamic tension because I hold back against EA with my slightly bent left arm.
I used to do this, when putting, only. The "push me pull you" version of E.A. Not sure how you resist but I did it with my left hand as opposed to the shoulder. I too have a slightly bent left arm and left hand.
But I dont any more. Not since hearing that Homer saw no use for EA with a bent left arm.
Im thinking that at issue, amongst other things, is a constant Radius. Now if you perfectly match the EA with a counter pull at the left hand, there is no issue but perhaps no point either. You've zeroed out the E.A.'s stretch of the left arm. For me it was a stretch between the two hands only. It felt like something but it was just hand tension as opposed to true EA.
Ive goofed around with a straight left arm , flat left wrist Crenshaw style so I could employ E.A. (Lynn encouraged me to try to try a flat left wrist when putting). It has a lot of benefits to it. Very much like Chip Basic, tons of structure to the flying wedges, you can get to both arms straight, its easy to isolate one arm as the power source (assuming you're Zone 2 putting) etc. But there's a lot of water under the bridge now , its hard to make a change like that.
I woke up this morning and started to think again- that is seldom good for me and does no one else any good at all. But here goes my ramble. I think what TGM is and what G.O.L.F. is. I think what a fine system of learning and developing a golf “game” it is. I am reminded that a basis is the book. What a fine but difficult book it is- thanks HK-. Then I see what a fine teacher and communicator and demonstrator of the “Alignments” and translation and understanding Yoda is- Thanks Yoda. We are all lucky. Then I recall Ben Doyle. “gentle ben” because he has a way of communicating to a big guy how to take all that will to attack into a gentle “touchy- feely” world. Then I read again chapter 4 and 5 particular 4-D and 5. A how it all fits because it is Imperative that I include 1. “Flat” left wrist 2. Lag pressure point and a straight plane line and all with Rhythm Balance and a steady head. Then I think about how I handle some of this and what is the feel. When I swing I have a very light grip. Barely touch the club. Swing my wrists and let the hands do what the have learned almost automatic. Sometimes I throw in a little #2 intentional uncock to get things” zipping” But that is my thing. When I hit I have am “more solid” grip and I use my hand more- I say hands not fingers. OK now I am ready for more TIPS and that is great because This has to be turned over again and again in my computer. Whaiting for the chicks to all hatch.
End my ramble in the lounge.
I really wondering how important accumulator #3 is? Tim Clark is known to be unable to supinate his left arm. On playing lesson he describes how he cannot even turn out with his left hand to get change from a drive in window!
Granted he's not that much of a chipper or a long hitter. But really accurate fairway player.
My point is that left forearm supination is part of the swivel process and it interesting to see how even top professional dont utilize all the accumulators to full potential. I think one the reasons his percentage in greens in regulation is so high that he cant under swivel or over swivel thru the ball offline.
