Here's a double pendulum model you can play with: http://www.maths.tcd.ie/~plynch/Swin...ependulum.html Notice how the "flat left wrist" (the first mass) stalls and collapses shortly after the "club" (the second mass) is released. Hit restart a few times and watch the "stroke". Then change parameters. Increase the first mass significantly and see what happens. Of course in the golf stroke we have to substitute this mass increase with lag pressure regulation (linear force). First of all, this is a great dialog that I didn't expect. I like the civil discourse. No doubt the hands slow as the heavy clubhead begins overtaking at release. But there is also a supporting mechanism; that is a turning left shoulder and an extending right arm (paddlewheel motion) providing resistance, because they are supporting the flat left wrist and intended hinge action through impact. If this is part of what you mean by Basic Rhythm then I think I understand where you are coming from. Homer used crankshaft RPM as the model. Even though the piston is connected to a crankshaft spinning at 3000RPM, the piston is going from 0 to 75MPH in less than 9 inches (my rough estimate). If there was a way to measure piston RPM, it would be much higher than the crankshaft as it accelerates to full extension, but that's not the what the gauge on my car is measuring. In the golfing machine, the crankshaft is the left arm flying wedge rotating through impact. Everything supporting that includes spark plugs, fuel, air, and oil. If those are out of whack, its time for a tune up. __________________ Bagger 1-H "Because of questions of all kinds, reams of additional detail must be made available - but separately, and probably endlessly."
