Not entirely sure what you mean here. Maximum sagitta should only be in the middle and reduce as you go to the edge. I don't see any evidence of a hole in the pic of the mirror surface. If the curve is spherical then your strokes will be smooth and without any sticking/slipping. Just a nice even drag over the whole stroke. The surface of the mirror should also look nice and even with no areas that have obviously coarser pits.
