[[ TMRCA is estimated for clades by average variance or GD from an assumed
Coalescence or Divergence age estimate of a clade is made from the average
tmrca of the N(N-1)/2 pairs of haplotypes of the sample collection.
The latter will be less than the former. I am sorry if the difference of
those two entities, conceptually or computationally, can not be seen. KN]]
