Could this be the "secret" of using Right Arm Thrust when Swinging? That is, using your Right Arm to Accelerate the Club Longitundinally (lengthwise).

Using the Right Arm to Accelerate the Club Longitudinally is the classic Right Arm Swing. The procedure I've described above is Left Arm Swing (because the center of the Clubhead Arc remains at the Left Shoulder, i.e., it is not transferred to the Right Elbow).

Again, though, we have a both a semantics and 'feel versus real' problem here. That's because, while the Right Arm is active in a Right Arm Swing (and also in a Right Arm Hit), the Left Arm is not active in a Left Arm Swing. Instead, it is essentially inert and provides only a structural contribution (as part of the Primary Lever Assembly and the Radius of the Stroke). It is Accelerated by the rotational transfer of the Body's momentum (in contrast to its Acceleration in the Right Arm Swing by the right triceps). And the Lag Pressure thus produced -- and which drives the Club -- is sensed in the Right Hand's #3 Pressure Point. Hence, a strong Right Hand Feel in a Left Arm Stroke.
