I'm not sure what the ratio between Beta_cutoffs, Exact_matches and
Alpha_cutoffs is, but I do know that 90% is usually used to the describe
First_beta_cutoff percentage.

100% * (Nodes that fail high on the first move) / (All Nodes that fail high)

If your First_beta_cutoff percentage is less than 90%, than there might be
something wrong with the moveordering.
