With a Stationary Pivot, Basic Motion, Back and Forth and Zero #3 Accumulator, the Clubface is Opening and Closing to the Plane Line. That's Left Arm Primary Lever for sure, but its guided and regulated by the "Straightening of the Right Arm with its Paddlewheel Action". No?

I think that if you use your right hand for anything but sensoring (and possibly that too - because you can't sense without applying some pressure) - and combine it with zero (and not just close to zero but zero) accumulator #3 - you will disturb the rhythm. The only exception is when you steer, such that PP #1, #2 and #3 forces the left wrist to be flat at all times. But without steering and without accumulator #3 lag any pressure from the right hand will disturb the rhythm.

IMO
