There are other problems as well.  _most_ (but not _all_) computer operators
will play me anytime my rating is _higher_ than theirs.  But not when I am
lower.  Humans won't play me if I have broken something and caused my rating
to drop a couple of hundred points.  They become suspicious that I have fixed
the problem and that the program is greatly under-rated.  And then there are
the ones that like to prepare trick book lines and play one game here and there
to use the trap...  particularly playing games with colors.  If you play me one
game and get white, you can wait until that game is out of our histories and
then pick the time to match me to get white again.  And again.  This has
happened on several occasions.

No end to the ways a rating can be inflated.
