7-23 Power Package Delivery Path

[Par71]

7-23. POWER PACKAGE DELIVERY PATH The three possible paths of the Hands down the Inclined Plane (10-23) are the Basic Delivery Procedures and the Delivery Line Equivalents (2-J-3) must comply with them. Per 2-J-3, the LINE Delivery Paths are "Cross Line" procedures and the CIRCLE Delivery Path is "On Line" in their relation to the geometric Plane Line. For a Circle "Equivalent," the Hands sense (5-0) a flat gyroscopic circular "orbit" path from Takeaway (8-4) to The Top (8-6) AND BACK AGAIN. The player envisions - is conciously aware of - a turning wheel RIM motion of the Hands, Clubshaft and Clubhead toward and on through the Ball. For a Line "Equivalent," the Hands, from Takeaway to The Top AND BACK AGAIN, sense the Clubshaft as a wheel SPOKE tracing a straight line extension of the selected Delivery Path. The player envisions - is consciously aware of - a straight line wheel TRACK motion (rather than its rotation) toward and on through the Ball, or THROUGH THE AIMING POINT. (See 6-E-2-1.)

Normally, Delivery "ACTION (Thrust)" is "Cross Line" - Delivery "MOTION" is "On Line," even at Low Point, because the Delivery Path Angle (direction) is ALWAYS the Right Forearm Angle of Approach (7-3) even with the Circle Delivery Path (1-L-9 and -10). (Study 6-E-2, 7-11 and 7-19).

Now I am confused.

1. There are Delivery Lines, Delivery Paths, Delivery Action (Thrust), Delivery Motion, and Delivery Path Angle (direction). I understand that Delivery Lines are used to guide the Clubhead and the Right Forearm, that the Basic Delivery Line is the true geometric Plane Line, and that one can use the Visual Arc of Approach or the Angle of Approach or the 10-5-E Closed Plane Line derived from the Angle of Approach as equivalents (2-J-3). I also understand that Delivery Paths are the paths the Hands can take toward impact (10-23). Can someone please explain what Delivery Action (Thrust), Delivery Motion, and Delivery Path Angle (direction) are?
   
   
2. How does a Straight Line Delivery Path relate to a Swinger's Arc of Approach (or true geometric Plane Line) Delivery Line? The Path of the Hands would be a straight line and their thrust cross line although the player traces (5-0) the true geometric Plane Line or the Arc of Approach with his right forearm and #3 Pressure Point?
   
   
3. How is a Straight Line Path of the Hands brought about, by the way, if the left arm is to remain straight (extensor action)? I had assumed that the Straight Line Delivery Path of the Hands was somehow caused by the Hip Slide / Axis Tilt, but according to 7-23:
   
   

   The "Axis Tilt" (2-H) allows a Line Delivery Path but does not require it.

   So, the player needs to do something in addition to the weight shift, hip slide, axis tilt to make a Straight Line Path happen. But what?
   
   
4. Also, I do not really understand the meaning of "from Takeaway to The Top AND BACK AGAIN" in the first paragraph of 7-23. The last sentence from 10-23-0 seems to allude to the same:
   
   

   The five Downstroke Paths are all valid for equivalent Backstroke shifts, also.

   Does that mean that for Straight Line procedures the Hands also need to take a Straight Line Path on the Backstroke? If so, how do you do this? Do you aim the Hands at the Aiming Point even on the Backstroke?

I hope somebody can help.
