Patrick, have you tried the Aiming Point procedure? If no, try it and see if you dont feel like you are Thrusting Down and Out , towards the Plane Line past Low Point all the way to Both Arms Straight, Follow Through.

You said "thrust along the plane" , you must, need to, thrust down the Inclined Plane. Our perception of things, our intent changes the geometry. Either for the better or the worse. Maybe the Aiming Point deal is better for you than Tracing? Maybe not. They are geometric equals but not exactly the same by any means......I bet you see some divots.
