how accurate is we gene it gave me me 4.23 % indian if its not indian what could they be picking up i have some unassigned on 23 and me

the rest pretty must coresponds with 23 and me results (except only giving me 18.29 % ashkenazi but when added balkan (which i did not get on 23 and me) and ashkenazi up it equaled about what my ashkenazi percentage was on 23 and me i did also recieve .01% chinese but since its not specified and its so small amount thats probably noise
