With two estimates in this thread, one at 85 kya and one at 100 kya I'd say
that - to the extent our model is accurate - your "confirmed" 70-80 kya

I am glad we had this thread : it turns out that with a proper collection of
haplogroupA haplotypes the 70000 - 80000 years estimates for "out of Africa"
(Y DNA) is confirmed. Thank you for making the calculations.
