I think we all agree there is no Plane Shift on the Downstroke as Els' hands come directly down the Turned Shoulder Plane.
However, because Els does not address the ball with an on-plane Right Forearm, the angle of inclination of the clubshaft (and his hands) are positioned several inches below the Turned Shoulder Plane. His hands don't arrive on the Turned Shoulder Plane until about shoulder high (the Top). That would be a single shift -- Elbow to Turned Shoulder.
My final answer is......zero shift.....nada shift.....in plain english no shift.
