Can you explain why the hitter does not have to rotate the plane lines to curve the ball?
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 ClubHead Path and ClubFace alignment of Sketch 2-C-1 #3 (which "they" say is "junk science" ).
"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-outClubhead 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?
Can you explain why the hitter (and not the swinger) does not have to rotate the plane lines to curve the ball?
Can't the swinger move the ball back or forward?

I believe its Hitters and Hands Manipulated Swingers vs True Swingers in terms of Grip Rotation vs Plane Line Rotation for balls played back of low point. The True Swinger allows CF alone to align Face , Head and Shaft. So by definition, there is no Grip Rotation (squaring of the face) for balls played back in the stance (or back of the clubs unique "straight away position") per 7-2 and 6-H-0 E and F.
We need some drawings here to make things easy (ish).
