this is not correct.  human ratings were used (IIRC) maybe up to 1993 at
the latest.  7 years washes _all_ the 'humaness' out of the SSDF rating
pool, since they have played thousands of games since the last human game
was included.

Interestingly, Crafty played in the Pan American a couple of years ago and
finished in clear first place, all by itself, running on a pentium pro 200
machine.  However, that doesn't help ratings at all, as there are so many
players, you won't see a 2000-rated player until the last 2-3 rounds, after
you have played 4-5 players between 1400 and 1900

It absolutely wouldn't.  Crafty played 7 rounds and had one draw.  It's
performance rating was under 2400.  Because the first few rounds you will
get low-rated players.

Yes it did.  The problem is that there are few GMs and hundreds of 1500-1900
players.  That does nothing for a rating.  :)
