I am still a bit worried on the reliability on these strength determinations, because the Nutters seem to get an inconsistent result. They seem to underperform against the Clobberers, and I don't understand why. The Nutters are a very tricky army to handle. They are highly deficient in backward moves, and the only piece that at least can step 2 backward (the Fibnif) can only step 1 sideway at the time. This makes it very difficult for them to catch a passer. Fairy-Max often is not aware of that before it is too late. Perhaps an engine that would intentionally keep at least one piece as 'rear guard' would do much better with the Nutters.
But this problem should occur against any army, so it cannot explain the poor score of the Nutters against the Clobberers.
