If I understand it correctly, haplogroup assignment by a vendor is typically based on their haplotype's closeness to a 'norm'. It is only those who have had deep clade SNP testing that are really accurate. And that accuracy periodically can get re-arranged by the scientists. Recent revision of the Y-DNA tree has resulted in EVERYONE who was classed R1b by FT DNA (as well as those who got the SNP tests for exactitude) in our surname project to be moved to an entirely different Haplogroup.
It started with "assigned" R1b, then we got "assigned" R1b3 and "assigned" R1bc and now (if I read the latest Y-DNA Haplogroup chart Family Tree included in "Facts & Genes", Volume 7, Issue 3 correctly) I believe it's "assigned" R1b1b2* unless one of our members has additional SNP testing to show up a difference at the 2nd or 3rd panel level of SNP testing.
And since I don't even have a copy of the SNP markers of the one individual in our project who was "classified" as one of the I groups, I have no idea at all as to what his haplogroup has become.
This _IS_ a technology that is still rapidly being refined, doncha know?
