What were the RMS estimates on the two tests?  And if you made a guess 
about the reading sigmas, what were the RMS sigma outputs?  It would be 
interesting to see if the two RMS estimates were within the error bounds, 
if so, such a result would be expected, if not, better investigate to see 
what went wrong.
