    TMRCA estimates based on surname cluster milestones and variable years per YSNP

    I just completed a 30 minute video that shows how to create much more accurate TMRCA estimates than the YSTR and YSNP only approaches. This approach first creates TMRCA milestone dates for surname clusters. This information is not used by other YSTR only or YSNP only approaches. This approach assigns any YSTR or YSNP branch the TMRCA = 1000 AD for the L226 Irish haplogroup where there are 31 known surname clusters to date. Also, for 55 of the 133 YSNP branches, this method uses variable years per YSNP which eliminates a lot of the statistical variation that exists.
