Please study:

6-C.
7-3
7-11

Then:

10-11 for your final answer on the use of #3 by a swinger.

10-11-0-3 PRESSURE POINT #3
(above) can be either active or passive (6-C-2-A) Accumulator #1 indirect drive (7-11) of the Secondary Lever Assembly (6-A-3) (2-K). That is, actively as Accumulator #2 Axe Handle application for Hitting (10-3-K, 10-19-A) but passively as Accumulator #3 (6-B-3-0, 10-19-C) or with a Right Arm Swing (7-19). Lag Loading (10-19) and Delivery Line (2-J-3) requirements. It is Loaded (10-22) per 7-19 as required by Component 19 application being employed (10-19). Study 2-G and 6-C.
Remember, with Swinging, Pressure Point #3 must have a Feel of being rotated a quarter turn at The Top with Standard Wrist Action (10-18-A), just and only because of Loading Action direction – no actual movement of anything. So from The Top to Release, the Loading put the top side of the Clubshaft against the first knuckle of the forefinger. But with Hitting there must be NO change whatever.

When the Wrists “Swivel” back to the Vertical Position (4-C-3) during Standard Wrist Action (10-18-A) per 6-B-3. Pressure Point #3 may – but need not – return to its “strong” position (Aft side of the Clubshaft). That is – if left in “Top-of-the-Clubshaft” position it becomes a Weak Single Action Grip (10-2-A) and the interchangeable equivalent to 10-2-C for Swingers. But both are improper for Hitters using Single Wrist Action (10-18-C).

A swinger does not have to employ #3, but certainly can...
