My autosomal test at 23 and me (new AC tool) discovered that i have close to 6.0% (5.8% if not mistaken). Under the old ancestry painting test it was 10%. Any way, there is also 0.6% NA that came up in the Ancestry Composition tool. People there says the east Asian could be reflective of NA ancestry and vice versa. I know of no East Asian family, but my great grand father always said his father was NA. Both carried the surname Oxendine which is common amongst Lumbees in N.C and S .C. My paternal great grand parents were from the west Indies!
