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.
