And variations in Elbow Bend and/or location during Release will disturb Clubface control by the Right Arm,

Right arm (or left if you are a warlock) The manner in which the right arm straightens will influence a list of things but particularly the #3 accumulator.

6-B-1-0...Active or Passive, the straightening Right Elbow with its Paddlewheel Action, powers, guides, and regulates the #3 Accumulator Motion..."
6-B-3-0 THE THIRD POWER ACCUMULATOR
Power Accumulator #3 is formed by the angle established between the Clubshaft and the Left Forearm. Accumulator #3 should never be “Out-of-Line – instead, it seeks to MAINTAIN its radial alignment with the Left Arm and Left Wrist vertical to its associated Plane. So, basically, Accumulator #3 Hand Motion (4-D-0) is “Clubface Control,” “Rhythm Control,” and “Roll Power Control” of the Right Elbow (7-3). Study 2-G and 7-20.



I am not suggesting clubface control is a function of the right elbow, but it is without a doubt an influence.

Players that have what I call a "deep impact" e.g. Trevino, Hogan, Furyk etc. have very stable clubfaces that do not flash closed.

This pic of Trevino shows very clearly that having ample right arm bend through the impact zone goes a long way to quieten the clubface. Trevino's just whispers!

Okie,

I think you are right on the elbow bend to clubface control, its something I am playing around with, the deeper I can get it the straighter the ball flight, usually a slight left to right pattern, which I think all three of those golfers above employed.
