Am I missing something here, but I never got the impression from the
original posting (sorry I cannot remember his name) claiming that he and
his wife estimates to .1 degree accuraccy just because they expressed
magintudes with multiples of .1 degrees fractions.  The way he explained
how he got to those numbers is about the same as when I say something is
25.4mm long.  This is not to say that have measured to .1mm accuraccy, I
just converted from 1 inch.  The absolute accuraccy of his estimates might
still be .5 mag. (or worse) without expressing his results ending in ".0"
or ".5" mag. 

Just my 2c's.
