That is a misconception. A common flail (with a thong) definitely shows turn and roll. The golfer's flail is "only somewhat flail-like" (because of the way the hinge pin works). But even the golfer's flail can Cock and Uncock and Turn and Roll (2-K). Study pictures 2-K #4 and #5: They both represent the golfer's flail.



PA #2 may precede PA #3 or not (Sequenced Release vs. Simultaneous Release). But PA #3 may not precede PA #2.

PA #2 does not cause PA #3. Nor does it release PA #3.



The idea is that more force is applied to the ball when it is struck with an object that is still accelerating at Impact, rather than with an object that - although moving with speed - has already stopped to accelerate. That applies to all Power Accumulators. So, for maximum power, no Power Accumulator should be fully expended before Impact.

Ok.

How about the power being transferred by PA3 (Roll Transfer Power), where did that come from? If that came from PA2, would it be correct to say that PA2 power would be transferred by PA3 efficiently even if PA2 is fully released already at impact?
