I score DYS 534 = 17, while one of my 62/67 matches scores 15. This is the
5th fastest mutator. FTDNA class it as a difference of 2 on that marker, otherwise my match would be 63/67.
Do FTDNA always classify this marker in such a way? I seem to recall cases where other two step mutations are only counted as a miss by one.
Any views?
