Yoda,

There must be a huge application of ball position and its effects on plane line and plane angle shifts. Meaning, the further back the ball is played the more up-plane it is, so the clubhead will move Down and OUT more to low point. OVER TIME (maybe a long time) wouldn't a ball position well back of low point shift possibly a turned shoulder plane angle to more of an elbow plane angle. Closer to low point would do the opposite.
