what is the magic of the right forearm?

The other cool part about the On Plane Right Forearm at Impact Fix is that you can approximate the Angle of Approach per 2-J-3 . . . Imagine a line on the ground PARALLEL to your On Plane Right Forearm through the Ball . . . this approximates the Cross-Line (out to right field) Angle of Approach.

Is this the preffered method in TGM of making a back swing vs, the right shoulder take away?

Thanks
