Until Lynn gets back on line.

The golfer’s Flail is the Left Arm and the Club, the Primary Lever that applies force on the ball. Centrifugal Acceleration and Momentum of the Throw-Out releases accumulator#2 to produce its In line Condition. That is what a flail does- it goes from out-of line to In Line by a whipping CF action. Farmers trashed wheat with two sticks and a leather strap. A golfer’s Flail is the left arm and club with the left wrist being the leather strap. Many pics of Google of flails.
Since CF produces the In-Line to sqaure the clubface, I will say it is for Swinger's. A hitter uses a driving right arm to release acc2.

Now the Law of the Flai- 2-K gets you to an Inline sqaure clubface. Acc#3rhythm with an Hinge motion is needed to complete the shot.
