These ratinglists are completely seperate (AFAIK), so we can't be sure one list
hasn't "drifted" up or down relative to the others.

If a program scores worse in in bullet than in Blitz (against humans that is),
then I suspect the program has some sort of time management problem, for the
advantage over humans in bullet seems very large.
