Bioengine,

I agree that the pivot is very important. Zone 1 is where people should start BUT you cannot feel # 3 PP (clubhead) , trace the plane line (shaft/sweetspot plane) as well as execute one of three hinge actions (club face)on command with the pivot. The pivot does all the heavy lifting the dumb brute if you will. The hands are the command post, and without the science of relationship (Geometry) a golfer will have nothing but a dumb brute pivot with moron mittens! Hell, before reading Chapter five of TGM I did not even know how to grip the club properly. I have played pretty good golf for 20 years now. No amount of physics can teach you to put your hands on the club correctly. I do not think a chasm exists between action and motion, as you seem to suggest. Designating a percentile participation score seems silly.
