I think my confusion stems from whether we're talking about the angle of approach on the inclined plane, or it's visual equivalent on the ground. For 10-5-E, the one on the ground is the reference for constructing a new plane line, right? But once you've got the new plane line, forget both the old plane, and any new angle of approach visual equivalent. Trace the new plane line and the clubhead will (approximately) visually cover the (old visual equivalent) angle of approach through the bottom of it's arc.

I think I have further confusion stemming from the fact that not only does the clubhead have a path that can be described in various ways, but so too do the hands have a path, which can be described in the same way. So for example, in the 10-5-E procedure, does the right forearm operate parallel to the old (clubhead) angle of approach (that is the new planeline, and so directly behind the club), or does it have a new angle of approach? I'm guessing the former. If so, would the latter be using the closed plane line without using the "angle of approach procedure"?

• The Angle of Approach that the player sees on the ground represents the actual Angle of Approach insribed on the face of the Inclined Plane. Hence from the player's visual perspective, they the same.
  
  
• Yes, you disregard the old Plane Line once the new 10-5-E Closed Plane Line (proxy to the Angle of Approach of the old Plane) has been set.
  
  
• Once 10-5-E has been established, the player tries to visually cover it with his clubhead. In doing so, what actually happens is that he is tracing his new 10-5-E Closed Plane Line. Remember, every stroke must have a Straight Plane Line being traced (whether or not your are actually trying to trace it), and you are tracing the 10-5-E Plane Line if you're using 10-5-E.
  
  
• As you have correctly stated, the hands must necessarily travel on a different path when using the new Plane Line, simply because the whole Inclined Plane has rotated, and the Hands always travel down that Plane.
  
  
• The Right Forearm must always trace a Plane Line, regardless if it's Open, Square or Closed. If you're using 10-5-E, your Right Forearm will be tracing 10-5-E. In other words, you would set up your Right Forearm Angle of Approach (which is a different concept to the Impact-Low Point Angle of Approach concept) on 10-5-E. Ideally, with your Clubshaft in-line with your Right Forearm, you should automatically be tracing 10-5-E by using the Clubhead to cover the new Plane Line (The Angle of Approach procedure).
  
  
• Using the Closed Plane Line without the Angle of Approach procedure simply means that you are not using the Angle of Approach as a Delivery Line to guide the path of your Clubhead. Hence there is no need to 'cover' the Closed Plane Line. In either case, your Right Forearm is always tracing the base of the Inclined Plane.
