I had a question. If all Europeans have Basal Eurasian in them since all Basal Eurasians had a few % of SSA in them (Out of Africa) then why does SSA show up for some Europeans on the Gedrosia K3 calculator but none for others?

On my Gedrosia K6 I had no SSA. Just Natufian but when I ran the K3 it came back with 1.58% SSA. This makes no sense.

Why doesn't the Basal SSA show up for everyone?
