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?

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.
