Homer Kelley disagreed, in fact Yoda said in 2006,

Homer Kelley told me:

"You can 'clown' the Backstroke," i.e., take it back however you want (and from whatever position you want), but at the end of the day, per 1-L #20:

"For any given Line of Compression, every Machine must produce identical Impact Alignments."

I think Homer was much less concerned with the backswing than people here today, and much more concerned with getting to the Top/End with enough physics potential to deliver those Impact Alignments with as much clubhead speed as possible.

Very interesting observations. I am finding working hard on the basic geometry with my students, and my own swing is paying off faster than anything I've ever taught or studied. My students, however, are not nearly as advanced as you and Justin...
