If I set my thing up to only play 3 0 against GM's its rating would go through
the roof.  Mofongo's rating was 2997 before it played a 3 0 match with Garompon.

You wonder why this guy's formula says "!blitz" now?  He knows he's at a peak
and he wants to sit on top of the list for a while.

The point is not that Mofongo does well against humans, it is that it is *only*
playing humans and it is *only* playing at extremely advantageous time controls.

What you are seeing is a kid with a hot computer and the desire to maximize
rating via formula variables.

Have you stopped to wonder why the rating of "crafty" is lower despite having 4x
as much horsepower?

It won 16 games of 5 0 in a row against a suicidal IM, after having a nice run
against a few computers.  It started out at 3077 against the IM and picked up a
hundred points.

Fine, nothing wrong with this, but it proves nothing, either.

Can't compare via these means.
