I'm not sure how you come up with the 6th cousin number, but Relative
Finder isn't looking at averages -- it's looking at long consecutive runs of
matching SNPs that can be traced back through the generations. Relative Finder
doesn't declare that everyone is your cousin, just a limited subset of the
customer database.
