So I bought the Pro version of admixture studio, and I have to admit it's great fun running my data through all the calculators. Most of them seem to be generally accurate for the bigger chunks, such as NW Europe, SW Europe etc.
Also what's great is that almost all of the calculators are giving me a consistent Berber chunk of between 3 to 5%, which is consistent with my dad being NW Spanish, but which Ancestry DNA (whose raw data I am using) did not pick up at all.

However I'm also getting some outlandish results that come and go depending on the calculator. One calculator will give me 0.4% Papuan, which will then not appear at all in any of the other calculators. One will give me 0.3 Inuit, which in turn will not appear in any of the other calculators. One calculator will give me a sliver of Omotic, which will not appear...etc etc etc...

I'm no expert, and am not sure how to interpret these minute portions. Is there a cut-off point percentage-wise, below which I should not put too much stock in the results? Should I be focusing mainly on the larger chunks?

Thanks...
