"Summarizing:

1. To determine the exact waist bend, 'shoot' the Plane Line with your 'Right Shoulder rifle.'

2. To maintain the Right Shoulder on its Rotated Shoulder Plane, 'Trace' the Plane Line with your 'rifle barrel!'"

Each club produces a different amount of waist bend. When playing, you would have to do 1. on every shot. It's bad enough to have 14 different plane angles, but to also have 14 different waist bends would be overwhelming. I have never seen a top player who used a Rotated Shoulder Turn which was on plane in both directions.
