  1. The row <D> contains average Robinson – Foulds distances to the species tree, the row rDL contains the correlation coefficient between distance and alignment length. “Perfect” are numbers of inferred trees that coincide with the species tree. “Bad” are numbers of inferred trees whose distance from the species tree is greater than 0.25. “PQ is better” and “PQ is worse” are numbers of trees whose distance from the species tree is, respectively, greater or less than the same distance of the tree inferred by PQ, “P-value” is the p-value of comparison the least two numbers by the sign test
