You are a "thinker",
Michael. And, you have a late-teens son who is an excellent player. Neither of you have seen me personally.
Add to that, you've been on my site from the beginning (Jan 2005) and you read me the year prior (2004) on at least two other sites. I can only conclude that you've found something of value here these past seven years, else you would have been gone long ago.
Now . . .
You come of late with orientations of
TrackMan as the "be all and end all" -- your own and those on another site -- whose "zeroed" Path and Face alignments, BTW, agree totally with TGM's aligned Club
Head Path and Club
Face alignment of Sketch 2-C-1 #3 (which "they" say is "junk science"

).
With whose top guy --
Fedrik Tuxen https://sites.google.com/a/pganation...fredrik-tuxen/ I spent almost two hours -- mano-a-mano -- on Friday of the PGA Show. In his own words:
"These are very
complicated questions."
"We
average the impact interval [Impact, Compression, Separation].
"We allow for
one degree of error".
Fine and dandy to me.
Maybe not so fine and dandy to the ball.
With this whole idea of
inside-out Clubhead Path (from
Impact to
Low Point) and
On-Line Line of Compression at
Separation (indifferent to Low Point) -- and, per 7-2, "Ball back" (Hook alignment) and "Ball Forward" (Slice alignment) -- what say you to your own question?
