I would note that in the text:

"At the top of the Backstroke – even at End (10-21-C) – mental construct a line form the #3 Pressure Point to the Aiming Point."

he specifically says "top", not "Top", which makes me think the mental straight line construction AND the thrust is at the top, even if it's the End, and not the Top. After all, you hardly have time to mentally construct anything once the DS is under way. Also, thrusting from the End would deflect the straight line effort to start from the Top automatically.

Thanks Joe

Thing is Homer never showed a photo of the straight line hand path beginning at End. End being anything above Top , right shoulder high. Some guys have their hands way up over top of the their head at End. For them to get back to Top a place from which they can drive straight line they have to retrace the top arc. In so doing their hands move BACKWARDS (not forwards) Down and Out . From Top however they move FORWARDS DOWN AND OUT. Thats a critical difference , perhaps accounting for why Homer depicted straight line Hand Paths as commencing from Top at the highest.

To thrust straight line from an End where your hands are above your head say would be very cramped assuming a straight line hand path . You'd have to bend your left arm there by losing radius width. It'd have a super steep angle of attack.

Aiming Point Procedure , Thrust is a Right Arm Action . Hitting or Swinging , Actively or Passively the Right Arm is always Driving. Put another way to my mind, the right arms motion swinging or action hitting is very much a throwing like motion . Where does it throw towards , thrust towards ? The Aiming Point. This thrusting drives the circular orbit of the club head.

6-C-2-A THE ESSENCE of Clubhead Lag technique is that it is always both Aiming AND Thrust. Passive – it is primarily Aiming the Lag Pressure. Active – it is the primarily Thrusting the Lag Pressure Point. The Orbiting Clubhead does not seek out the Ball – it seeks out the Delivery Line. But never directly – only via the Right Forearm and the #3 Pressure Point per 2-F, 5-0 and 7-3. It is guided along that Line to the Both Arms Straight configuration by the straight line thrust of the #3 Pressure Point toward the Angle of Approach quadrant of the Ball – or Aiming Point – per 1-F, 1-L-9/10, 2-J-3 and 6-E-2.

Summing up the Right Arm action - it is always a straight line effort and/or motion and normally is strictly Clubhead Control. In the meantime the Flat Left Wrist (Clubface Control) under every condition or situation is concerned only with arriving at Impact, Vertical to the ground in the process of executing the selected Hinge Action. So, per 1-F the Hands are correlated but independent of every other factor." Practice every phase, over and over until mastered.
