Does a position of the right elbow at the top as if the right hand tries to pull an arrow out of a quiver mean a "loaded right elbow"?

Naw sir. The position of the right elbow at the Top is an alignment with respect to the lever assembly that you are loading be it the primary lever assembly (left arm and club) or secondary lever assembly (club). So the Right Forearm should be opposed to the lever that you have selected in your loading. With swinging you are loading the secondary lever assembly thus your left wrist is loaded. And your right forearm is directly opposed to the clubshaft. The left wrist is loaded and then unloaded via the throw out action of cf.

The "loading of the right elbow" is the hitters procedure . . . drive loading. Your loading the ENTIRE primary lever assembly left arm and club. Thus your elbow is typically in a punch position. So at the top you are loading your right elbow inorder to DRIVE (push) the primary lever assembly out with your right tricep . . . like delivering a punch.
