Number of quartets for which each pairwise metric produces a topology that agrees better with that found in the literature.

The quartets examined are among those for which the disagreement between the two metrics is quantitatively the worst. We note that, when compared to , produces a topology that agrees with literature much more often. “Neither” indicates the case where neither metric produces a topology that agrees with the current literature. “Undecided” indicates that it is not possible to establish a ‘correct’ topology on the basis of current literature.
