I believe that while I was attempting to correct the hole in the center I already inadvertently began a parabola/hyperbola. Basically, it is like the hole almost got bigger and expanded more towards the edges. I have not tested the SA yet on it so I do not know how exact it is. The greying/shadows on the mirror are pretty hard to read sometimes. I will just continue with the regular big "W" stroke to attain a better parabola. Any other suggestions? |
