I don't get the same result as you either, because indeed, my
fill-column setting is not the same.  But one thing you're doing wrong,
is to put a single space after end-of-sentence dots.  Emacs considers a
sentence ends with dot space space, not on dot space.  If you add spaces
after the end of senctences, then justifying the text will give better
results.

With a single space after RTFI. :

9/19/12 Worked 9.5 hours.  Spent 1 hour misc.  Spent 0.5 hour
RTFI. Watched Mitutoyo vid of IMTS QIF demo.  Exchanged email messages
with Bob Brown.


With two spaces after RTFI.  :

9/19/12 Worked 9.5 hours.  Spent 1 hour misc.  Spent 0.5 hour RTFI.

Bob Brown.


You can also skip over sentences with M-e and M-a, and compare what
happens with a single space and with two spaces after end-of-sentence
dots.
