three planes, circle patterns of hits, concentric, small ring, medium ring large ring, if the hits are higher in the small ring then you are in trouble.
However, I'm not sure what your resolution and repeatability is on your CMM to distinguish between the hits if the part is convex by .00005.
Light bands if it is flat enough and reflective.
Make them intentionally .0002 concave so you can test it with an indicator fast and easy.
