so the zero shift is done on the turned shoulder plane, with a flat shoulder turn the 'best' option?
The Backstroke uses the Flat Shoulder Turn, the Downstroke uses Downstroke Shoulder Turn. Two different motions
quote:
the sweetspot works up the turned shoulder plane right from the get go and on the way down the rear shoulder, sweetspot and shaft will work back down the turned shoulder plane?
If you were to draw line on photo or video to represent the Shoulder Turn Plane Line/Angle it would not be from the ball back up to the Top. It would be the Inclined Plane using the clubshaft, right forearm to a spot that has been determined based on the Flat Shoulder Turn of where the Right Shoulder is. Note that when Brian did the analysis of David Toms, he said he used the 3rd or 4th frame to identify the Turned Shoulder Plane spot at the top.
The sweetspot and the shaft will only reside on the Inclined Plane when the clubhead has been turned or rotated. This is done during the Backstroke with a turning motion and during the Downstroke a roll (swivel for swingers) will take place and at that point the sweepspot and shaft will no longer be on the Inclined Plane.

at times in the backswing the shaft not be on the T.S plane?
If the Inclined Plane is drawned as Homer did, the shaft should be on the Inclined Plane. That is not to say a shift couldn't occur, but then it wouldn't be a zero shift.

how can you be on plane at the start of the backswing if the sweetspot and shaft are not both working up the same plane angle? .. picturing it my head it looks like the shaft would be pointing well outside the target line if the sweetspot starts up/back on the T.S plane and you havent set up the shaft/forearm on that plane(possible without a straight rear arm?)
Homer described 'being on plane' in reference to the base line of the inclined plane. His diagrams in chapter 2 clearly show the Inclined Plane, Shaft Plane and Sweet Spot Plane. Only the Inclined Plane and Shaft Plane are parallel to each other.
Yes without having a stiff left arm you can have the clubshaft and right forearm (not arm) be on the Inclined Plane using the Shoulder Turn Plane Angle for the Inclined Plane. And you maintain your flying wedges...
