I have comptemplated it, but don't do enough mirrors to move away from
the Foucault test.  Plus it has something to do with the way I figure. 
I graph each  step of figuring using a spread sheet.  This allows me to
'watch' the profile and see how it is changing in reference to that
dreaded/oft malaigned tolerance envelope.  I guess I could see using the
null and a final 'collaborating' test, but that would be about it.  But
then again, I may just not understand it enough to know how it would
help me during figuring.  Geez.  It has to be either very early or very
late on your side of the world right now. ;-)
