Let us discuss the possible reasons for getting the CLUB OFF-PLANE on the BACKSWING and DOWNSWING, and the best ways to STAY ON-PLANE. I'll start with a couple, then others chime in.
Off-Plane
1. Right Forearm off-plane at Address. I realize that many(most) do set up with the forearm off-plane, but this is one possibility.
2. Changing the BENT RIGHT WRIST angle. This should not change at all throughout the Stroke, except briefly in the front part, between Follow-Through and Finish, when the arms MIRROR the BACKSTROKE conditions.
"getting the CLUB OFF-PLANE": More dominant action of the hands/arms than shoulder turn. Why? Because the range of movement (degree of freedom) for the former is a lot more than the latter.
"the best ways to STAY ON-PLANE": Spin around an axis.

"Sustain (Yang/陽) the lag (Yin/陰)" is "the unification of Ying and Yang" (陰陽合一).
The "LAW" creates the "effect", which is the "motion" or "feel", with the "cause", which is the "intent" or "command".
"Lag" is the secret of golf, passion is the secret of life.
Think as a golfer, execute like a robot.
Rotate, twist, spin, turn. Bend the shaft.
