The three following plots show that the most highly supported constraints selected by MaxTiC tend to agree more with sequence divergence as measured by d[donor]-d[recipient], where d=clade-to-tip divergence.
I think similar plots could be used as an alternative to the new proposed figure 2, as a way to convey the following points:
individual constraints tend to agree with sequence divergence, in particular supported constraints
some outlier constraints exist: those constraints that are highly supported yet disagree with sequence divergence are potentially interesting in that they may reveal areas of the trees where the molecular clock is mistaken.
Such a reasoning could be used as a transition to the discussion of the biologically relevant constraints.
