Are you talking about the right forearm being on the inclined plane at impact here?
Is what you mean by the RF return to the right angle of approach?
At Impact Fix, the Primary Lever is In line with a Flat and Level Left Wrist and the Right Forearm Wedge is "Intact" with a Level and Bent Right Wrist and the "Forearm" is Against the underside of the Plane while the #3 PP is On-Plane tracing the Plane Line. The Right Forearm while against the Plane is Angled Down, Forward and Outward. That's the Forearm Angle of Approach. It's not just the Angle, but it's the Angle of the Right Forearm when the Wedges are Intact, especially the Right Forearm Flying Wedge.
