I doubt there are many who can tell whether you'r wrong or right. It looks good to me anyway. I was actually standing by here waiting for an answer from someone of your caliber.
One question though;
Do you really trace the plane line with pp#3? I don't mean geometrically, but mentally. In a monitoring sense? Do you think about it when you strike the ball?
I do a lot of tracing at address. My mindset is arch of approach. But when I've started the motion, the tracing basically happens in virtual reality.
The monitoring I do with pp#3 is basically for lag pressure and discontinuites in the hinge action.
I don't monitor where the club is going. Not conciously anyway. But I probably do it subconciously. It seems like I already know where the clubhead is and what it takes to move it through impact. So a lot of focus on the ball and the intent of the shot, but not much monitoring once I've started the motion.

Yes. I try as long a trace as the length of swing permits.
Three feet aft and Three feet forward is a definite "Drawing a line with a Pencil". With a flying wedge waggle, Three feet aft of the ball, the trace feels like a right to left dragging a broom where the wall meets the floor, and Three feet forward the trace needs right arm straightening to keep the broom against the baseboard.
During the actual swing, all of that blends together and feels like a long sweep while straightening my right arm. But it's definitely drawing a line with a sweeping and straightening motion of my right forearm/hand.
It's really important to me to feel that on every shot because it helps to feel like I'm dragging the #3 PP pressure through the ball as my right arm straightens. I like the feel of dragging the club and I want to keep it dragging and not take over the shot.
I don't rotate my arms or Wrists (Swivel) which is probably why I'm able to sense the #3 PP so well. I just use a simple Horizontal Hinge. The Impact Swivel is the automatic outcome of my Hand Path moving Down-Plane. Simply Straightening the Right Arm while moving Down-Plane returns the Clubface to Vertical for Impact.
Those are my feels. They worked really well this year. I really tried to keep things simple. Fairways, Greens, Bar, Nap; in that order.
