 It can calculate all possible outcomes for a single game leg in about 5ms, so effectively instantaneously.
 Full-game calculations take a little bit longer and are not exact (since it isn't practical to simulate all possible full game states.)
 However it can easily simulate a million random games in about 80ms in the worst case, which should provide estimates accurate to within about 0.2%.
