Daryl-can't believe I beat you to it!.Another point,I believe the #3accumulator roll is the answer-or at least #3 acc.The right forearm is on plane at address and impact .The left arm retains acc#3.The left arm is never on plane -except when the waist bend is such that the shoulder turn is on plane in both directions(mostly putting).pp#3 is always on plane.
