And where have YOU been, 12 pc? This place isn't the same when you're absent.
I wasn't as impressed with Miyahira's blog this time as I am usually. He seems to be more on home ground when he discusses topics between the shoulders and the feet. But I found some of the photos very telling.
I think good rhythm is required to eliminate flipping, or to delay it until past impact.
HK basically introduced rhythm as a relationship between the left arm and the club. But there's more to rhythm than just left arm and the club. Quoting 6-B-4-0:
Quote:
"Left Arm Power" in any form or amount can still be considered #4 Accumulator Action. Otherwise it actually substitutes for the Pivot to introduce the circular motion required to produce Centrifugal Force
I think the word "substitute" is important here. This substitution is really a sort of arms flip. When what happens in the shoulder socket i geometrically very similar to what happens when the left wrist breaks down. As long as you swing your arms around the pivot your left shoulder will not be well aligned for an effective rope pulling. You will get max benefit from the pull from your left shoulder when the lead - lag relationship between the shoulder pull and the left hand is coordinated. I am tempted to say constant, but I'm not sure about that. The release of club changes the game as it happens.
When you blast off the chest in a swinger's procedure you will have a lot of Accumulator #4 lag pressure while you're blasting and not much when the arms fly off the chest. You will have some effective shoulder turn generated lag pressure for impact, but you better max the usage of Accumulator #4 while the pressure is really on. It is the part of the swing when the shoulder turn and the arm is 100% synchronized that gives the "effortless" power. And I believe that goes for other stroke patterns than 12-2-0 as well. I have personally come to regard the pp#4 pressure more as a monitor than a power source. I can basically hit the ball equally hard with more or less PP# 4 pressure at the top as long as I am able to synchronize the shoulder turn and the arms.
Further, I am convinced that it is the "pulling the left arm out of it's socket effort" - combined with structural support from extencior action (or driveloading) that produces the most power. PP# 4 is like a soft cusion by comparison. But maybe that's because I'm not a hardbody
It is very common - particularly amongst high handicappers - to have an underdeveloped shoulder turn and then compensate by swinging the arms around the shoulders. They can't feel the weight of the club because the left shoulder is running on empty instead of pulling a heavy club head with 5th gear leverage.
I think poor rhythm between the pivot and the arms is a root cause to many bads in golf, including the powerless flip.
