    The predictor notes that values above 50 indicate a good fit with the haplogroup. However, I'm getting a 55 for Q, and 51 for R1b. With the values being this close and both over 50, would FTDNA likely not be confident in my haplogroup and suggest further testing, or would 55 to 51 likely be separation enough to say "probably Q"? Or is it even a stretch to guess what FTDNA might predict if Athey's predictor has it this close?

    Thanks!

    Scott,

    I understand that FTDNA uses their own prediction algorithm and not Athey's.
    Also, having a larger dataset of SNP confirmed results might make their prediction system produce better results.

    Anyway, if they found such a close result as in your example it is very likely that they would go for the SNP test.
