Jim,

I've second guessed you on this, I had a feeling that this is what you'd
say, so I went right ahead.
Short-ish strokes (a tad shy of 1/3rd) "W", three times around over ten
minutes, gave the following readings after leaving for an hour to stabilise:
-

0mm (centre)    1.59mm  3.58mm  5.01mm(edge)            All +ve, coming away
from mirror.

I think it is getting there, the LF/Ro(max) has dropped from 7.15 to 6.23.
I may be able to give it some more tonight.
BTW. What do you use to calculate P-V, RMS & b? Is this from TEX?
