Pivot / Non-Pivot Stroke Delivery may be found in 6-K-0 and 6-L-0.
How do we decide which one to use? Does it differ for Swinging and Hitting? Can you use a Pivot Stroke Delivery on the Backstroke, and a non-Pivot Stroke Delivery on the Downstroke, and vice versa?
Power Package Delivery refers to the Delivery of the Assembled and Loaded Power Package Down Plane to Release. Hence, it is a Downstroke concept, not a Backstroke concept.
The use of a Pivot Stroke automatically implies the use of a Pivot Delivery. Only where the Pivot Motion is incidental would it not be used to Deliver the Power Package. That is because both Hitters and Swingers properly utilize the Pivot to overcome the Clubhead Inertia during the Start Down. In other words, the Body Pulls the Arms and Club into the Downstroke.
However, once the Lag has been Loaded and the Right Shoulder has reached top speed, Muscular Thrust (Right Arm Drive-Out Action) takes over for Hitters and Centrifugal Force (Left Arm Throw-Out Action) takes over for Swingers. In other words, the Hitter uses the Body as a 'backstop' (the equal-and-opposite reaction) for their triceps-driven Right Arm. The Swinger, on the other hand, continues to use the rotary motion of the Pivot to Accelerate the Left Arm (via Momentum Transfer).
