[Yoda]

I've edited my Post #6 above to include more information and references. For Labor Day's 'early responders', it's worth a re-read.

BTW, I fully understand that such detail is of interest only to amateur afficienados and professional Instructors. The former use it to their own edification and advantage. The latter, likewise, but even more, to that of their students. The 'rest of us' should take what we want and what's left over, in the words of my NY friends, Fuggeddabouddet! An alternative is to dump it in your Incubator and come back later.

For Instructors: Should you teach the TGM material 'chapter and verse'?

My opinion -- unless you are in an academic setting -- is a resounding "NO!".



Instead . . .

Teach Motion (12-5-0).

Motion aligned Geometrically (2-0); learned Mechanically (3-0); and performed Subconciously (14-0).

As only a few in the world know how to do.
