Your inputs as well as the others have been in the incubator for a while.
I have been reading the book regarding the pivots involvement in Basic Motion. My conclusion, wrong or right, is that there IS/WAS a reason for Homer to propose the Zero Pivot in Basic Motion.
Here comes some quotes from the book:
"without the Key of Educated Hands per Chapters 4 and 5, more information only means more confusion."
"The Hands are the “Command Post” for all Feel processing."
" Educate your Hands (9-0) to execute the Delivery Path "
"key to control of the Golf Club is Educated Hands."
Well you get it.
With a zero pivot, you must educate your hands.
Don´t you think that Homer would have recommended a little pivot in the basic motion, if he thought that IT(the pivot) would be to an advantage for the process of educating the hands?
It is a whole other story if there are ANY tourplayer that chips/pitchs with zero pivot.
But trust me on this one - they have EDUCATED HANDS
