Intraclade variance is always hard to interpret, and there are - as
you notice - additional challenges when you use that technique on a
paragroup rather than a proper clade.
One thing you can definite NOT infer from a paragroup's variance is
that you are estimating the TMRCA for the upstream clade. In other
words, the variance of R-P312* does not lead to a TMRCA estimate for R-
