Sweet Spot

[DOCW3]

From as early as 1-L { The Machine has three functions-to control A) the Clubshaft.....and...The Inclined Plane is Clubshaft Control}, there is consistent reference made to the clubshaft and in 10-13-D to a Downstroke Clubshaft Plane. 2-F explains that there is a Clubshaft Plane and a Sweet Spot or Swing Plane and makes the following points:
-both planes always pass through the Lag Pressure Point.
-except during Impact, the Clubshaft can travel on, or to-and-from, either Plane.
There is also what seems to be a "qualification" in 2-F: "unless otherwise noted, Plane Angle and Plane Line always refer to the Center of Gravity application."

How should a student use this information or what is its significance to an effective study and implementation of the components? Should we take the wording at face value or is some mental adjustment necessary? Is #3 pp a sufficient interface?

One of my favorite topics, 'The Qualifier'.

As I understand it, when discussing plane angles and plane lines, it is NOT the clubshaft line unless so noted. It should always be the sweet spot line.

If you think about it for a minute, for anyone depending upon centrifugal force in their swing, the 'Center of Gravity' makes perfect sense.

What I take out of it is that PP#3 is a sufficient interface only if I maintain the Right Flying Wedge. The wedge maintains a strict relationship that places the forearm and clubshaft at a specific plane and angle(due to the frozen right wrist bend). Because according to Homer, the sweetspot plane and clubshaft plane are essentially identical, I only have to deal with my right forearm, not either the clubshaft or sweetspot, to maintain my plane. Thus the "tracing the plane line" with PP#3 works to stay on plane. And can be traced by a flashlight in your hand or a dowel.

Yoda has a very detailed explanation of the sweet spot and clubshaft planes in the wedges, gyroscope and aiming point thread. Here is the paste and copy:

DDL,

You have correctly observed that the Target Line lies just outside the Plane Line of the Clubshaft (as depicted in 10-5-A/B/C). However, unless otherwise noted, all TGM Plane references -- including the Plane Line -- are to the Sweet Spot Plane, not the Clubshaft Plane (2-F). And that Plane Line lies directly on the Target Line.

For many years, Homer Kelley thought in terms of the Clubshaft Plane and not the Sweet Spot Plane. But over time, he came to realize that the Sweet Spot Plane was Boss. Here's why:

1. It is the Sweet Spot that sends the messages (through the #3 Pressure Point) that enables the Player to sense and control the Clubhead Lag through Impact. This Sweet Spot is sensed only when it is in Motion (because only then does Centrifugal Force exert its Pull). Otherwise, the Player senses the dead weight of the Clubhead -- and not the pinpoint that is the Sweet Spot -- through the Shaft.

2. The Clubshaft itself does not remain on a constant Plane, nor does it maintain a constant Straight Line Baseline. Instead, it rotates around the Sweet Spot and thereby alternates between its own original Plane and the Plane of the Sweetspot.

So, embrace the Sweet Spot Plane and disregard the Clubshaft Plane. During the Downstroke, you do indeed Uncock and Roll while Tracing its Straight Line Baseline with your Right Forearm and Right Forefinger #3 Pressure Point (12-3 Sections 6 and 9/10/11).

This is the correct application of the Third Imperative (2-0)...a link in the chain of destiny leading you to your best golf.

DDL~ Thanks for the information. I had done a sweet spot search with no findings. How he closes and the selection of "embrace" may indicate an answer to my question.

We have the book teaching including photos supplemented by many forum posts including dowel drills, details of the right forearm flying wedge and video clips aligning the right forearm at address. We have been taught about Impact Fix, aligning and positioning the clubface and Planes. For me, the shaft and the plane(s) it moves on has been an important part of the programming. Accepting what Yoda has said would seem to be a sufficient reprogramming.

I am better prepared when the subject enters the discussion .
