Dude . . . . Come on man . . . Let's move on from this . . .
Basic Motion is basically 2 feet back and 2 feet thru . . . but BASIC TO ALL MOTIONS IS THE MOTION OF ARMS AND PIVOT . . . and Pivot as defined by Homer Kelley can be full pivot OR NO PIVOT AT ALL . . . that'd be Zero Pivot.
Do you have the book?
I have the book, but can't read it (in the right way). If you are getting upset with me - let me know. And regarding understanding - there can be total understanding or no understanding at all -- that'd be Zero Understanding.
