The percentage of Ysearch entries not from FTDNA or the Genographic Project
is so small as to be almost irrelevant.
Ysearch's primary value, in practice, is to make up for the many
inadequacies of the regular FTDNA account matching. FTDNA account matching
was designed for heavily represented populations that have undergone recent
rapid expansions. It focuses almost entirely on very close matches--no more
than a GD of 7 at 67 markers. If all we had were FTDNA's regular account
matching, most customers outside a few heavily represented ethnic groups
would quickly give up on the field entirely.
Up until now, Ysearch has rescued this inadequacy by providing a way for the
less represented ethnic groups to cast a wider net for near-matches, in
order to interpret their results in some reasonable way.
