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.
