I do trace the plane from the top. with both #3 pp (feel only no pressure an is on top of club before trigger) and the "butt" of the grip which is as close to #2 pp for tracing as possible. I try and LOOK! LOOK! Look!
I see myself using a plane well above the elbow plane.
I might mention that I am working on basic motion both swing and hit and it is difficult to control lag with basic motion swing but hit has a better means of lag pressure control.

I also have a plane board. Made from 1/2 in insulating foil covered foam. Basic motion hit the shaft stays flat on the plane but basic motion swing (or complete motion) the hossel strikes the plane abter #2 rtrigger and as the sweet spot is rotated to perpendicular to the plane. (about half way between trigger and low point (45 deg. accross plane. I, myself may be oversensative to this mechanics because years ago I did some serious fencing (Epee) and the point is controled by the pads of the index finger.
I thing the two problems are mechanical an exist in all swings because I am at a loss of how to correct them in the geometry.

It sounds really good. It sounds like you have a good grasp of what you're doing and what you're doing sounds good. Maybe the problem is in another component or components?
