Mutations are events, and you are not counting events. You are
looking at something different: the genetic distance between the
extant haplotypes in a sample and the modal haplotype for that sample.
It's not clear its a useful thing to count at all (since variance
incorporates all that information, and more). But if you are going to
count it, most people would call it genetic distance.
