With regard to your question, WHAT IS OF UTMOST IMPORTANCE IS THE LOADING OF THE SHAFT. If you go much past top you start loading the knuckle on the top of the shaft instead of the pad of the finger on the back of the shaft. I'm loading my right elbow TO DRIVE THE CLUB THROUGH IMPACT and Yoda's loading his left wrist TO DRAG THE CLUB THROUGH IMPACT. It's really all about the loading, not the prescribed assembly point. Top and end are good visual checks for the instructor, though.

Now THIS was one great post! Great stuff, Ted!
