James:

I hope you'll accept this as a constructive criticism. Writing wavefront 
error results in the form "1/X.X" wave makes it harder than necessary to 
compare them. Also, entering numbers as text strings in a spreadsheet kind 
of defeats one of the main purposes of a spreadsheet, which is that you can 
calculate other things with those numbers.

Also, what are the +- numbers in the MRR summaries? +- 1 standardad 
deviation? +-2? The range?

One thing I think would be interesting would be to report the spread in 
results where available from multiple Robo runs or multiple interferograms. 
I'd like to see a comparison of the relative precision of human eyeballs 
vs. a mechanical device with automated data reduction vs. interferometry.
