I'm confused on what is bold.


10-13-B FLAT
This is a relatively flat Backstroke Shoulder Turn which places the Shoulder “On Plane” for any Plane Angle with a flatter angle than the Rotated Shoulder Angle. A Flat Down-stroke Shoulder Turn can serve only to impact a circular motion to the Stroke, but almost irresistibly “Off Plane.”

10-13-D ON PLANE
After a 13-B or 13-C Backstroke Shoulder Turn, the Right Shoulder moves toward Impact precisely on the preselected Down-stroke Clubshaft Plane, establishing and supporting the Power Package Delivery alignments. When the Shoulder can’t quite reach the Plane, it is better to use a steeper Plane.


Hey, can I get in on this party?

In regard to 10-13-B FLAT. I believe your bolded "almost always irresistibly Off Plane" is the Startdown's equivalent to the pure Shoulder Turn Takeaway in Startup and the basic problem there in. Namely, the shoulders are not (given a Flat Shoulder Turn in startdown) traveling on the Inclined Plane and therefore are likely to take the Hands or Power Package with them on their off plane meanderings.

Pivot Chain and Sequencing etc demand that the Shoulders and not the Arms provide the initial movement in Startdown for Total Motion shots and so its best to align the Shoulders to the Inclined Plane in Startdown. 10-13-D On Plane. (In Startdown)

All of this suggests that the shoulders dont ideally merely turn on the same plane back and down. Flat Back gets the Right Shoulder closer to Shaft Plane relatively speaking (compared to Rotated which would have a higher associated TSP angle) and then On Plane going down. Luke described this to me as the right shoulder painting a reverse "7" on the back wall of his hitting station. Notice how the top of the seven is flat and then a diagonal towards the ball. This portrays a TSP which is on the Shaft Plane I guess. Straight Line Delivery Path which requires Hip Action.

So the 10-13-B Flat going back lowers the Right Shoulder some and then given a Slide Hip Turn, Axis Tilt in transition (or before, see Hogan) the Right Shoulder is further lowered to a Turned Shoulder Plane that more closely approaches the Shaft Plane for it move 10-13-D On Plane. If this TSP actually matches the shaft plane, then no further plane angle shifting is required, if it only approaches the shaft plane then a shift or shifts (the more shifts the more you approach Circle Path) will be required. But its less of a shift than if you didnt use Axis Tilt.

At least that is what I make of 10-13-D's "better to use a steeper plane". If Im correct, which remains to be seen, it should probably read something like "When the Shoulder cant quite reach the Shaft Plane, its still better to use this TSP plane angle than a higher one".

You know when you try to rewrite Homer you quickly understand his preference for brevity. Consider the previous paragraph a Wiki guys.

Some wonderful G.O.L.F. in that post. Thanks OB!

One situation when ones Right Shoulder cannot reach the Plane, is when swinging on the ELBOW PLANE.

I'll repeat that for 12 Pc. Bucket.

I think that Homer was speaking directly to Bucket and descendants of Ben Hogan. Use a Steeper Plane. Doing so will give your stroke Right Shoulder support for the Power Package and eliminate the need for a hazardous Plane Shift.

Quote:
10-6-B TURNED SHOULDER This reference point is primarily the point reached by the Right Shoulder after a Flat Backstroke Shoulder Turn. But any other controlled Shoulder Turn can also provide an acceptable reference point. See 10-13-0. This Plane Angle has far better performance characteristics than any other because any Plane Angle Shift is very hazardous. This procedure does not refer to the disruptive Shoulder Turn Takeaway – which is always too “Flat” and/or too “Low” making a Plane Angle Shift mandatory and usually unintentional and unsuspected. Study 7-3 and 10-24-F.

Sorry that I am not quite understand.

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.

How do I know if the Rt shoulder is on the right plane in the downswing?
