DNA evaluations change over the time, as the sample sizes increase. For instance, someone who was previously believed to have 25% DNA from a region in Europe can be interpreted vastly less or more depending on how accurate the sample size is. Also, because generations of people migrate and intermix the understanding of regions will change as well.
I for instance, completely lost an estimated region of my DNA that was previously listed as "high confidence" with 16% of my total DNA. It's competely gone now and merged into another region, based on the increased accuracy and algorithms from the company. I'm not overly surpised from this, but I do have a clear understanding that my DNA is closely shared with that other region. What that tells me is, even DNA analysis will not give you a completely accurate determination of who you are. But, it does give you a very good idea where you come from. For people who have no clue who their parent is or where that parent comes from, it is really genuinely interesting to get that data. It becomes less interesting in other ways, especially if you have your family lineage documented and unquestioned for hundreds of years.
So there is some huge wiggle room for interpreting the data. I have a feeling that this is sort of like that South Park episode where (Stan's dad?) was trying to prove to everyone he was native american and was doing everything in his power to prove it to everyone. I don't understand Warren's efforts other then she finally found a strange way to prove to everyone she is very strongly possibly, at one point sharing DNA with native americans. Because our understanding of DNA is fluid, she should have probably become a bit more fluid about her own history.
