Daryl,
Before you put too much thought into this - let's keep it simple.
No, it doesn't function "normally".
#1 it goes from supplying power (assuming #3 pressure point has some pressure)to providing no power (regardless of the amount of number 3 pressure point pressure).
#2 There is no "overtaking action" when you have a zeroed out number three accumulator - the clubhead doesn't move when you twist your left hand in place with a zero number three accumulator. You need some #3 accumulator to have an "overtaking action". See 6-B-3-A last sentence. Lynn knows this - he was probably thinking of a different context when he originally posted to your question.

Just trying to save your sanity.

Mike, I understand what you're saying and it makes perfect sense to me. I'm more than satisfied with yours and Yoda's answers.

I think that we all see it the same way. That although the amount of power generated by the #3 Accumulator is the Left Hand/Clubshaft Angle, the motion of the Right Hand Paddle Wheel and the Straightening Right Arm, which controls that Power, is still present. It still exists.
