"The Right Elbow Center is just what it says. Namely, you Hit (or Swing per the last paragraph) from the Elbow itself. It is a Stiff-Wristed "Batting" Motion with the Right Arm Driving the Club and with the Elbow serving as the Center of the Motion."
Can we think of driving the elbow toward the ball?

I don't think so.

According to the bold text we can think of driving the club towards the ball with the right hand And we move the right hand by rotating the right forearm around a "stationary" right elbow.

I take it as a given that this right elbow turns together with the pivot as soon as it has been reconnected with the pivot in the down stroke and that this togetherness remains intact until the pivot has met its delivery requirements. I am no quite sure what those requirements are though.

If Yoda would care to go deeper into those delivery requirements I for one would appreciate it.
