I wasn't speaking in reference to any particular haplogroup, I was only speaking
in regard to what should be an easy updating of DYS452 in the database. I
didn't address the issue of updating DYS463.
FTDNA, like virtually all labs testing for genealogical purposes, reports DYS452
high. The Ysearch convention is for DYS452 to be high, and it is the high value
that is entered when someone does an auto-upload to Ysearch from their member
page. The problem in Ysearch is the values that are low, regardless of how they
