    I agree. I would even go as far as to say that even 25% of something can be very grey depending on the ancestral region.
    Paper trail:

    25% Russian
    25% French
    25% German
    12.5% Polish
    6.25% Danish
    6.25% Swedish

    K16: Estonian_Latvian_Lithuanian 2.5%, Finnish 5.83%, French_Belgian 4.17%, German_Czech_Austrian 49.17%, Irish_Scottish_Welsh 7.5%, Norwegian_Swedish 15%, Polish_Belorussian_Ukrainian 14.17%, Saami 1.67%

Ancestry is great due to number of matches -- I can easily put people into buckets. FTDNA is great due to Y and mt and a recently-discovered cluster, and because I have my parents on FTDNA, not Ancestry.

    The ethnicity estimate is not great on FTDNA -- it ignores my central/western Europe (German and Sweden) and dumps it into 85% British Isles and 15% EE, when I'm not EE at all and the British Isles is too high. Amusingly my sister and I get identically inaccurate results. It's best on 23andMe and now good on Ancestry (Ancestry is good and bad in different ways for my sister and me).

    That said, I've never once regretted testing at FTDNA, and love all the projects.
    Funny that you say that as I have easten euro i get none of and my British gets minimized, i get around 70% west and central european with the rest british and NA..

    I thought it might be because my eastern dna and british combined to create a very high west and central result but your results look to confirm this.

    Paper trail ancestry to the best of my knowledge:
    English (possibly containing some Welsh ancestry) 31.25%, Eastern European and Eastern German (Galicia, Poland) 25%, Scottish 17.96%, Scotch-Irish 12.5%, French 8.2%, Native American 1.95%, and Colonial American, 3.125%, which cannot be determined with complete certainty: there is Dutch (at least 1.36%) and some English. The rest could include Spanish, Norwegian, German, and French, but these percentages would be minuscule.

    I agree, it seems to be more accurate for people who are less mixed, but I feel like that wasn't as much the case before the update, so for people that are more ethnically mixed, the update seems like a regression in accuracy.

    For me it was 100x better before this white washed update. It was reasonably accurate, now its not.

    How is the update "white washed"?

    Speaking for myself here, but it was overly simplified. Granted some trace regions that were probably noise were eliminated, many of us experienced complete removal of certain categories that made up a larger %. For me, my 25% Italian was made up of 13% Italian, 6% Caucasus, 3% Iberian and maybe 3% Middle East (i dont recall at the moment). They simplified this to 10% Italian.

    Then there was the Italian/French thing. Its almost like they used an oracle to get middle of the road results.

    I've thought about this as well. I lost 4% Irish, 1% Iberian and 20% Europe West for 2% France - I think those contributed to French anyways, maybe some GB. I was glad to have my 29% GB refined, to what? I can't say - some mix of Germanic and England/NW Europe.

    The more I keep staring at my EE and Baltic, the more I keep shaking my head; but perhaps this is a result being too admixed for their calculator as discussed above. 34% EE, 13% Baltic and 1% Finland is too much given my paper trail. I don't know if that is even possible with inheritance patterns; could be wrong, just seems statistically less likely.

    I think they are just trying to streamline the results to appeal to the masses more than the dna geeks.

    so they cut Italian from 13 to 10; what did they cut Caucuses, Iberian, and Middle Eastern to?

    who knows. I got a bunch of Germanic, and 1% Finnish, lol. 6% French also

    regarding the old estimate, like you mentioned in the Ethnogene thread, Ancestry would put a full blooded Italian (southern at least) at 70% Italian 30% Other usually Caucasus, Middle Eastern/N. African etc. Some one who is half Italian would get roughly 35% Italian, 12-15% Caucasus etc.. which my Aunt had. I had 13% Italian, 6% Caucasus etc... so the math made sense more or less.
