Well, I wrote a lot of nonsense today (my statistic lessons are 20 years
ago), but what about this conclusion:

gnubg 1623 over all wins
bgblitz 1519 overall wins

j.s.d = sqrt(27.3+27.3 + 27.38*27.38) ~ 54.6

(1623 - 1519)/54.6 ~ 1.90

1.90 --> 97.1% confidence that in the overall competition (1 bot against
three bots) gnubg is better than bgblitz. That's one way we compare the 
reliability of move rankings, so it should be right here also, shoudn't 
it?
