Sorry that I am not quite understand.

- If the right shoulder cannot reach this plane.
- one situation is swinging on the elbow plane.

If you choose the elbow plane, then can the downstroke clubshaft plan be the elbow plane? Therefore the right shoulder no need to redirect to the TSP?

Also if swing back based on elbow plane then at the top should the right shoulder not on the TSP?

Can a hitter hit on both plane, directly straight down?

At address and through the ball for structural (RFFW) and tracing (the straight plane line) reasons the Right Forarm is ideally on the same plane as the clubshaft's lie angle.

The Right Forearm is said to be on this plane when the Right Elbow is on this plane. This is the Elbow Plane one employs through Impact. To accomplish this and a Level Left Wrist, adjustments must be made to your Head position, knee bend, waist bend, distance from the ball etc. These adjustments, if not done at Impact Fix will necessitate an identical adjustment dynamically when you are swinging......not the best thing for your consistency. This is a major cause of faulty Impact Alignments.

The Turned Shoulder Plane (TSP) is a line drawn from the Plane Line through the Right Shoulder when it's "turned" to its position at Top. This Plane Angle is dependent on many things including the type of Shoulder Turn employed. Generally the Flatter the Shoulder Turn going back the closer this Plane Angle is to the Shaft Plane or Elbow Plane. The Turned Shoulder Plane allows the Right Shoulder to take the Power Package down the TSP towards the Plane Line in Startdown. An On Plane move of the Power Package via the Right Shoulder referred to as an On Plane Shoulder Turn. Flat back and On Plane coming down. The shoulders dont turn on a single plane for the Standard Shoulder Turn anyways.

However the TSP is not the same Plane Angle as the Elbow Plane and so the Plane Angle of the Inclined Plane must shift to this lower Elbow Plane angle prior to Impact. This is achieved as easily as it was to shift to higher Plane Angle in the Backstroke if you Addressed the ball with a Level Left Wrist at Fix. It just sort of happens as the Right Elbow unbends, the reverse situation of Right Forearm Pickup. If you Pickup you must let it down, CF helps out in this regard.

The reference in 10-6-B to "any Plane Shift being hazardous" relates to a selection of an Inclined Plane Angle other than a TSP angle at Top which would necessitate a shift back to a TSP angle prior to an On Plane Shoulder Turn in Startdown.

Logic holds that any plane shift is hazardous yes but some shifting does happen. Keeping it to a minimum is what its all about while using your Right Shoulder to take the Power Package down plane as the initial move in Startdown. For this to happen you have to employ a TSP angle. The closer to the Elbow Plane angle the better.
