Does swinger must use pitch elbow and hitter use punch? Elbow positions does not differ Hitter or Swinger?

Loading Action determines Elbow Location. Elbow Location determines Hinge Pin Alignment when the #3 Accumulator is controlled by the On Plane Right Forearm Wedge seeking its Angle of Approach. So Yes, Swingers use Throwout which Aligns the Horizontal Hinge and Hitters use Driveout which Aligns an Angled Hinge Pin.

The Physics of Hinging is, that, Hitting or Swinging, “Roll” is actually imparted by the turning torso and/or the orbiting Arms per 2-K#4 and 2-K#5 as described in 10-18. Practice these motions first with open Hands per Chapters 4 and 9. The point to be learned here is that the Club, because of the Flat Left Wrist, must always travel at the same RPM as the Arms and reproduce the Hinging inherent in the selected Lag Loading procedure (10-19) per 4-D, 9-2 and 9-3, regardless of Clubhead Extension velocity. See 2-P and 7-18.

However, those with educated Hands can use their Hands alone to create (mimic) any Hinge Action. This application is more effective for short shot procedures but it's truly an accomplishment. Mind in the Hands, Finesse.

The Hinges are actually “mounted” at the Left Shoulder but the real control comes with moving or holding the Left Wrist in the positions called for by the respective Hinge arrangements. The Hinge Action Control is required only from Impact to the end of the Follow-through. Except, of course, when the Stroke Pattern Wrist Action dictates otherwise.
