For a difference of .002" over the surface, you are doing an excellent
job of measuring the surface error to begin with. Run those numbers through
TEX and you will see how good you really are. Please note that I consider
anything over 1/10th wavefront error to be acceptable and anything over
1/30th wavefront error to be wonderful for an optical surface.
