Two TGM GSEDs now claim that the science and many of concepts of TGM are no longer valid in light of their groundbreaking research!
They are about to release the results of this research, based on a paper by Miura, which uses a concept called "parametric acceleration". To summarize, the golfer from the top of the backswing, pushes his hands out wide without worrying about losing wristcock. When the golfer's hands get near impact, the handle of the club is pulled upward and inward, which apparently provides supersonic clubhead velocity and prevents a forward leaning shaft at impact, which is now, according to their research, no longer valid. He wants the shaft vertical at impact. His research also has shown that the concept of lag is wrong and something you don't want in a good swing. They also add in the thread, that you don't want a full pivot on the downswing, calling it "crazy", apparently calling for a slowing or breaking of the turning shoulders at some point. No more extending through impact to 'both arms straight', but rather a bent left elbow pulling up and in.
I've been trying to envisage a way to execute this new cutting edge science, and think I've got a good swing key. When your hands get near their low point, pretend that you suddenly realize your fly is open, and as your hands go by, envision grabbing the zipper with your left pinky finger and pulling upward. This one swing key should do the trick, and you could call it the "Open Fly" swing pattern.
A video preview is given on the Manzella.com site under the thread, "The release - w/ Mike Jacobs and Manzella videos". They claim that TGM concepts such as lag, plane line, rhythm, and hands ahead at impact are no longer valid in view of their blockbusting research.
