Stuck in Chapter 2 (2-0 General . . . the Principle of Golf) GM#73

This results in two basic impact geometries possibly as shown in 2-C-1 and 2-C-2. I say possibly, because Homer associated 2-C-1 with swinging and 2-C-2 with hitting; I think the opposite is actually the case.
The Line of Compression (LOC) is the Principle of Golf (2-0). When the LOC passes exactly through the center of the Ball per 2-C-1-#3, the result is maximum Compression and a Straightaway Shot. However, when that LOC does not pass exactly through the center of the Ball, a non-Vertical Spin is introduced. Given sufficient time and speed for the Venturi Effect (2-B), this causes the Flight Path (actual Path of the Ball during Flight) to bend away from the Flight Line (initial Direction of the Ball at Separation).
Producing and manipulating the LOC constitute the Mechanics of Golf (2-0). Properly executed, these Mechanics (7-2) enable both Swinger and Hitter to control Ball behavior. For any given LOC, there is only one Impact Geometry (1-L-#20), and this Geometry is the same for both Hitting and Swinging (Preface). Impact Alignments are established at Impact Fix per 2-J-1 according to the desired Ball Behavior, i.e., Straight, Hook/Draw or Slice/Fade. These Alignments differ for Pure Swingers and Hitters and are determined by the respective Mechanics employed (Plane Line Rotation or Grip Rotation per 7-2). Swingers utilizing Hand Manipulation employ the same techniques as Hitters.
Similarly, the LOC produced in 2-C-2 (Inside-Out Cut Shot), is available to both Hitters and Swingers. In fact, any Hinge Action (2-G) on any of the nine different Plane Line-Stance Line Combinations (10-5-0) is available to both Hitters and Swingers. Per 10-19-0, Hinge Action does not differentiate Hitting and Swinging.
So:
1. Swinging is not necessarily "the method of choice for those who prefer fading the Ball." Hitting may be similarly "preferred."
2. There is only one Impact Geometry for any given LOC through the Ball. That Geometry is equally available to both Swingers and Hitters.
3. The Hinge Actions illustrated in 2-C-1 (Dual Horizontal 10-10-D) and 2-C-2 (Dual Vertical 10-10-E) are likewise equally available to both Swingers and Hitters. That said, Horizontal Hinging is automatically produced by the Throw-Out Action of Centrifugal Force and is therefore most compatible with Swinging. Angled Hinging (not illustrated in 2-C) is automatically produced by the Drive-Out Action of Muscular Thrust and is therefore most compatible with Hitting. Vertical Hinging, on the other hand, always requires a deliberate Hand Manipulation -- for either Swingers or Hitters (6-B-3-0).
If executed correctly, the "Swinger" should draw the ball slightly with dual horizontal hinging per 2-C-1...

DG,
With an On Plane Clubhead Path Geometry (2-N) and Impact Geometry per 2-G, i.e., "...no glancing force except for backspin (2-C-1)," why will the Ball curve?
Is the low point in the diagram referring to the low point of the Swing (i.e., under the left shoulder) or the low point of the "Impact/Separation Interval"? Would it not seem to be the latter? Since the impact/separation interval represents only approximately 3/4" of clubhead travel, the diagram cannot be referring to the low point of the Swing. When viewed in that context, there is no "separation before low point"; i.e., the ball separates at the low point of the impact/separation interval.
I'll need to look at the diagram to see if I can understand your explanation. I've always assumed, and still believe, that the diagram refers to the low point of the stroke. The diagram depicts the clubhead force vector as straight ahead versus the "outward" force of a pre-low point inpact. Also, all the diagrams showing the angle and arc of approaches reference the low point plane line, which is the low point of the stroke. I don't believe I recall a reference to the low point of the impact interval anywhere in the book.
Even though I'm not sure I concur with your explanation, I appreciate you input. If I'm missing something, let me know. Thanks again.
Per 7-10 (page 100, first paragraph):
Normally, in the precision position per 2-G, the Left Wrist becomes Vertical to the ground at Low Point for all Hinge Actions. But, 'Vertical to the ground at Impact' gives a very desirable sameness for all Ball locations -- easily compensated by Clubface adjustment, without disturbing the prescribed Hand Motion. Both procedures are completely optional.

But, the left wrist "vertical at impact" procedure would still have the club moving downward, and outward, no? The 2-C-1 diagrams show neither at separation.
Any On Plane Impact -- either at or prior to Low Point -- must be Three Dimensional. The 2-C-1 diagrams stipulate Impact Geometry per 2-G and Clubhead Path Geometry per 2-N. Since these then are clearly Three Dimensional Impacts, please explain your comment: "The 2-C-1 diagrams show neither at separation."

Since there is limited or better said, scattered information on the right arm swing in the book, maybe Homer didn't get the opportunity or didn't think of putting an analysis of ball flight or ball behavior in the text as it relates to the differences between true swinging (automatic release) and right arm swinging (non-automatic release with thrusting action coming from the rear).
DG
DG,
Regarding Ball Behavior with Right Arm Swing and all other procedures as well, Homer said it all in 1-L-#20:
For any given Line Of Compression (through he Ball) every Machine must produce identical Impact alignments.
because I think Homer missed some important facts in this particular area, I wish to add the following: The best drivers of the ball on tour are high ball hitters that tend, for the most part, to fade the ball. The most accurate short and medium iron players are low ball hitters that tend to draw the ball. For me, this is a clear indication that there are two optimum methods for maintaining the line of compression through impact.

Ray,
Thank you for your contributions to this Forum. Please explain the "two optimum methods for maintaining the LOC through impact." It always helps to 'turn these things over.'
