AFAIK, it has not played lots of games. At least, if so, they don't have been
published. So, there is necessarily a large statistical variance. The size of
the variance is rather independent of the results. It depends on the number of
games which have been played. Since the number of games is small, you have a
large uncertainty. Agreed ?
