All Ancestry did was change the way it presented the ethnicity data (admixture is the better term actually). It wasn't a new test. So one day my home screen on the DNA page went from my old ethnicity breakdown to the new one. I knew it was coming so I actually wrote down the data and have it in a chart along with my new breakdowns. Same for the other kits I administer (except for the one that happened after the change).

I went from 90% Scandinavian in the old breakdown (with my mother only having 10% -- go figure) to 35% Scandinavian (with my mom bumping up to 37%). All of this with us having no known Scandinavian ancestry (although given the Norse/Viking influence of parts of England/Scotland/northern France this is actually understandable.) All of my categories (and the ones for the others I administer) start at 0% is the % is less than 10-15% normally.

The admixture displays at GedMatch are better, but more complicated in that you have several to pick from. Several of them break down European groups into different emphasis categories. Some of them are better if you have Jewish or Asian ancestry.

Still, way too much emphasis is given by Ancestry on the ethnicity when it is selling the tests. Given that it gets people to test and having a larger pool of people to find the person that might hold that one key bit of DNA I don't mind it too much.
