I think another hour of w-stroke (exclusively TOT) helped reduce the TDE on
my mirror. See picture from test 4 at:

However, the lines have developed a slight bow toward the outside of the
mirror (inside ROC). I think this means a slightly raised center? Also, I'm
a little afraid that the bowed lines are just masking the TDE and that it
has not really changed.

If the center is raised then it would seem that going for parabola would
just take a little longer but would fix the problem. Do I need to fix the
raised center to get a good judgment of the TDE? As always, I'm looking for
suggestions.

Thanks again for all of your help!
