Wow, what a great answer. That has really helped me a lot. One more question to follow up:

Should the Flat Left Wrist Swinger with zero accumulator #3 turn the left wrist on the backstroke and roll it on the downstroke or would that be a wrist action that should be avoided in putting? My idea is that as long as you have zero acc. # 3 and do not cock the left wrist on the backstroke a simple turn and roll of the left wrist would not qualify as wrist action at all.

With or without Wristcock, when a selected Hinge Action (Component #10) is used as a substitute for Wrist Action (Component #18 ), it becomes the 18th Component as well. In Putting (and other Strokes without additional Turning, Rolling or Cocking), this is termed Zero Wrist Action (10-18-G). In procedures involving Wristcock, it is termed Single Wrist Action (10-18-C).
