An analysis of Warren's DNA sample showed she had a Native American ancestor in her family dating back six to 10 generations.
From your post 269:
32 4th great grandmothers +
64 5th great grandmothers +
128 6th great grandmothers +
256 7th great grandmothers +
512 8th great grandmothers = 992 women or 0.1 percent
So how is it "wrong" to say:
However your math used generations outside of that range including fourth generation when the reported range was 6th to 10th and average of 8th.
