"If you stay static in this position, your clubhead travels at the angular speed of the merry go round (this is your body power). And to your point of view, your whole Power Package is static and ready to be fired as a hitter.
If you now drive with your right arm, your clubhead will travel at the angular speed of the merry go round PLUS the speed of the thrust."

What you seem to be saying is that the pivot-thrust throws the power package assembly intact at a certain rotational speed and that you can increase the speed of the clubhead by an active release of PA #1.

However, I understand the pivot-thrust as more than a throw of the intact power package assembly down to waist level. I see the pivot-thrust of a swinger as catapulting the left arm off the chest wall so that the left arm travels faster than the pivot thrust (merry-go-round) and then sequentially having the PA#2 release via centrifugal action so that the clubhead travels much faster than both the merry-go-round or the left arm (which is traveling faster than the merry-go-round due to the complete release of PA#4). Under those optimized conditions, I cannot understand how adding right arm thrust (active release of PA #1) can increase clubhead speed.
