[Yoda]

To get people to move their right shoulder downplane correctly one of the greatest sayings ever is to get your LEFT SHOULDER "up and back."

Because if you can do that, the right shoulder will go down and out.

I agree that, in practice and drill, players should be aware of the return of the Left Shoulder to its Impact Fix Location. But...

Do you drive the Left Arm (and Club) by pulling the Left Shoulder back to its Fix Location?

Or do you drive it by thrusting the Right Shoulder -- against the Left Arm and its #4 Pressure Point -- toward the Ball?

In my forty years of golf, I have never heard or read of a great Champion describing the Left Shoulder as his Driving Force into Impact.

Right Knee.

Yes.

Right Hip.

Yes.

Left Hip.

Yes.

Right Shoulder.

Yes.

Right Arm.

Yes.

Right Hand.

Yes.

But never...

Left Shoulder.

The Secret of Golf -- Clubhead Lag (6-C-2-0/A) -- is all about 'Dragging the Wet Mop' -- unrelenting, inert Clubhead Lag Pressure -- through Impact.

And despite the fact that the 'Wet Mop' -- the Left Arm, Club and its Dead Weight Inertia -- hangs off the Left Shoulder, you don't Drag it 'back-handed' with your Left Shoulder and Arm. Instead, the uncoiling Left Side is led by Hip Action (7-15) that "throws" the Right Shoulder Down Plane. This welds the Left Arm against the side of the chest -- the #4 Pressure Point -- and Delivers the Assembled and Loaded Power Package into Release.

Swingers use Centrifugal Force Body Power -- rotational Momentum Transfer -- to sustain this Clubhead Drive through Impact. Hitters use Right Triceps Muscle Power.
