Yoda, does changing the Geometric Center of the Right Arm Swing relocate Low Point to under the Right Elbow?
Yes. With the Right Elbow now the Stroke Center, the Low Point of the Stroke is directly beneath it. Remember though, that the Right Elbow location -- and hence the Low Point -- is constantly moving forward as the Downstroke progresses. Thus, at Impact, it ideally will be Located in front of the Ball.
