I have always had trouble understanding the following part of 7-3.
7-3. STROKES-BASIC
Right Forearm Position at the Top differs for the Angle and Arc of Approach Procedures. So their Elbow location and action differ also. … For Swinging (10-19-C) the right forearm should be precisely in-line with - and directly opposed to - the motion of the On Plane Loading Action of the Secondary Lever Assembly (the Clubshaft) and this alignment maintained through impact.
Question:Is the left wrist bent slightly to accomplish this in line relationship in order to maintain longitudinal alignment of the primary lever assembly?
