The Stoke Center for the Right Arm Swing is the Right Elbow. So Low Point is constantly moving forward in the Downstroke. If you want the ball to be struck before Low Point (which is the case for 99% of shots played, except the Lob Shot), the Right Elbow needs to be
in front of the ball
!
I believe this is a dead giveaway for a Right Arm Swing.
Also, because of the Right Elbow Center (rather than the Left Shoulder), the Swing Radius is shortened considerably
