Yes, "position along the plane, and vector direction off dead straight ahead" would have a big effect on the feel of the plane. But I think only when picking up or putting down, or starting and stopping the cut at the ends of the board, or waving the plane through the air, or planing with a skewed angle. I.e., only a fair amount of the time. But in all those instances, it is not the height of the CG or CE that matters, it is the horizontal placement. And it seems to me that Derek is concerned with the heights, since he is drawing a distinction between CE in BU vs BD planes.

I don't believe that "position along the plane, and vector direction off dead straight ahead" makes much difference during the bulk of a simple straight planing stroke.

For those two reasons, I specifically did not include position along the plane, and any vector in any direction off dead straight ahead in my suggested definition of CE.
