Let's discuss Turning Shoulder Plane for a while. And don't worry, I do not actually want to use it. Just perusing the book for items I don't fully understand, yet.
Per Chapter 11, the Basic Plane Angle (Club Shaft Angle) for the Turning Shoulder Plane is: Squared Shoulder Location. That's consistent with picture 10-6-D #1. And also with its name "Turning Shoulder" Plane. 7-6 says that each Basic Plane is named for its particular reference point and that one of them (must be the Turning Shoulder Plane) has a moving reference point.
So, to be On Plane with a Turning Shoulder Plane Angle the Shaft always has to be on a Plane that runs through the right shoulder. At Address the right shoulder is in its Squared Shoulder Location, so the Shaft has to be effectively on a Squared Shoulder Plane. As the shoulders turn on the backstroke, the right shoulder moves "in", and the effective Plane Angle of a Turning Shoulder Plane flattens. At the Top, it will effectively have become a Turned Shoulder Plane.
In order to address the ball with the Shaft on a Squared Shoulder Plane, Accumulator #3 has to be zeroed out almost completely (either by uncocking the Left Wrist at Address or by having the grip almost in the cup of the left hand).
BUT, in the early editions of TGM (up to the 3rd edition), Homer said about the Turning Shoulder Basic Plane Angle:
So my first question is: How can the Turning Shoulder Plane develop enormous #3 Accumulator travel and energy if Acc. #3 has to be zeroed out almost completely in order to get the shaft on the proper Basic Plane Angle to begin with?
In later editions (4th and 5th) Homer wrote in 10-6-D:
Double Shift, Single Shift and Reverse Shift all use the Elbow Plane, which is a much flatter Plane Angle than the effective Plane Angles that the turning right shoulder locates. And, in fact, the effective Plane Angle changes that go along with a Turning Shoulder Plane are even opposite to those that occurr with Double Shift, Single Shift and Reverse Shift: With a Turning Shoulder Plane, the effective Plane Angle flattens on the backstroke and steepens on the downstroke. With the Double Shift, the Plane Angle steepens on the backstroke and flattens on the downstroke.
So, question #2: What is the meaning of this reference to Double Shift, Single Shift and Reverse Shift in the context of the Turning Shoulder Plane?
Finally (question #3), what about a player who addresses the ball with the Club on the Elbow Plane and then either (a) takes the Clubhead straight back from the ball by raising the Arms vertically and imparting rotation from the Pivot (like 10-6-D, Procedure A.), or (b) moves his Arms straight back (like 10-6-D, Procedure B.)? What Plane Angle would he be using? Would that be considered a shift from Elbow Plane to Turning Shoulder Plane? A legitimate deviation of Turning Shoulder Plane? Or just an "X"?
