Ok bucket are you saying the right shoulder follows the left elbow pocket or does it drive it. I guess swinging you could follow it or in hitting you could drive it. How does this relate to the "mind in the hands". Perhaps this type of swing thought could prevent the OTT move or the underplane problem. I anxiously await further flywheel and platform explanations. Once I've gottem then pray for a break in the temp so I can go to the range. Sorry you have to work bucket. I am going to sit by the fire all day like most old folks.
I don't want to be presumptuous, in thinking that I can speak in place of His Royal Highness, Lord Bucket. But, I'll give you some opinions from a commoner.
In 2-H, Homer writes about the direction of the Right Shoulder:
"But the Shoulders do have crucial On Plane functions – synchronizing and aligning the Pivot Motion and Thrust with those of the Power Package (Chapter 6). “On Plane” Right Shoulder Motion is possible only by titling its axis – the spine. See 7-14. In this area the Left Shoulder is helpless. The geometry of Shoulder Control deals only with Right Shoulder, for there are no guide lines for Left Shoulder control of the Right Shoulder. Therefore, variations in Right Shoulder location will vary the Left Shoulder location at Impact and, consequently, the Low Point location as well as the Angle of Approach (2-N).
Being a part of the Pivot and the Power Package, the Right Shoulder must reconcile them by moving with the greatest precision for thrust, speed, direction and distance. (7-3) So the Right Shoulder does not flap around haphazardly – it has many responsibilities. And variations in its Impact location will vary the Right Elbow’s Impact Bend and so may alter the Impact alignment of the Clubface."
So, the Right Shoulder can have direction, because it can move toward a Plane Line. There's no specific direction in "swinging left", as there's no direction for the Left Shoulder or the Hips. The Hips rotate more on a horizontal plane than on the inclined Plane. Therefore, giving them any direction is haphazard.
As the ball and Plane Line get closer to the body with a shorter club, the Plane steepens. As the ball and Plane Line moves away from the body with a longer club, the Plane shallows. Therefore, a Shoulder Turn Throw differs in direction with ball location. We do have options or preferences in steeper versus flatter Planes, as Nicklaus and Hogan were both successful.
When the Right Shoulder, the #3PP, and the Sweet Spot are married together at Top and move in the same direction in Start Down, the forces are aligned for maximum efficiency. Divergent forces are simply less efficient, but are found all the time on the PGA Tour.
In my own 4 Barrel Hit, the Pivot Drags the Power package toward the Plane Line with a Shoulder Turn Throw (10-20-C). And, I follow with a Right Arm Throw (10-20-B). It feels like I’m throwing a baseball at the golf ball.
