    Radically different results for African-American regions. Thoughts?

    I took advantage of Amazon's $99 sale on 23andMe a couple weeks back and had my husband tested. He's mixed white and black. Got his results back this week and his African regional results are wildly discrepant. Ancestry believes his ancestry is predominantly (22%) from Congo and central Africa, whereas 23andMe doesn't get anywhere near that even if you include every "Broadly" category. 23andMe believes he's more than 21% Nigerian and Coastal West Africa (Sierra Leone, Liberia, Côte d’Ivoire, and Ghana), whereas Ancestry gives him 0% Nigerian and 1% Ivory Coast/Ghana. And the Benin/Togo and Mali results from Ancestry and kind of a mystery altogether.

    Anyone have any thoughts on this? Is Ancestry's algorithm just not very good for AA folks? Knowing the African slave trade routes, the new results just don't seem logical. Points to consider:

    1. Before the AncestryDNA update, his top regions were 11% Nigeria (which completely disappeared after) and 9% Senegal (which dropped to 1%) and he had 0% Benin/Togo.
    2. His LivingDNA results found him 30.9% Yoruban (which they described as Nigeria, Benin, Togo, Cameroon, Ghana, and parts of Niger and Mali), 6.8% East African (Ethiopian, Sudanese, Somalia, Tanzania, etc; something no other test has shown) and 2.5% Mandinka (which they described as Gambia, Guinea, Mali, Sierra Leone, Ivory Coast, Senegal, Burkina Faso, Liberia, Guinea-Bissau, Niger and Mauritania.)

    The last Ancestry update did that to a lot of people's African percentages, sucking them into Cameroon/Congo, Benin/Togo & Mali. Don Felipe has a blog post about it --> "Did Ancestry kill their African breakdown? (part 2)"
    Ancestry paper trail tally: 21.1% Colonial American (British Isles, German, Dutch, Swiss, French), 14.1% not traced past 19th Century United States (MD, NJ, NY, PA, VA), 7.8% Canadian (Ontario & Quebec), 40.6% German, 15.6% Czech, 0.8% British & Irish
