David - If I may break in, please - I have been reading data and sources for over a week - the grass is getting deep and I need to shave.
Should I first try to determine the Major Group - I,R,G D,F - whatever and then proceed to sub-groups? Or can I just jump to a marker under a subgroup and assume that a match means everything above is OK?
Next - ancestry autosomal results seldon hit the RSID exactly - they are sometimes close and sometimes not. Can I assume that something indicated there was no reason to report that rsid information? Or is this just random and has no intent of being useful in haplogroup prediction?
