The Arc and the Angle do not share the same Plane Line so to be precise its not just the Right Elbow position that differs! 2-J-3 is a big mess of worms.....hard to understand for a few thousand readings.

This makes no sense to me, are you saying you have two different baselines of the plane for hitting and swinging? In hitting you should be tracing a baseline that would be different than swinging for a square-square setup to hit a straight shot.
