Doug, if the screw holding the cartridge mounting plate is directly above the stylus, would rotating the cartridge change the overhang? I follow your post and it makes sense to me in every case except the one I mention.
It seems to me that if the cartridge is being rotated along a zenith axis which corresponds precisely with where the stylus tip meets the LP, overhang becomes determined only by the position of the arm pivot point.
I find cartridge zenith alignment to be one of the key advantages of the Mint LP protractor. It is very easy to align the cantilever with the tangent lines at the null points.
