Apologies for confusing your use of their summation formulas with
your use of their tools.

However, the summation formula used by Ken and the summation formula
used by James (if I am reading the archive correctly) appear to
effectively put more more and less emphasis (respectively) on the
most mutative markers. I agree that neither method employs an
explicit weighting scheme, but the effect is similar.

Anyway, the two formulas produce different relative ages for R-S21
and R-S28.
