I'm particularly curious of this 6% Asia Central category I scored. Could it be representative of Iberian ancestry? I score 1.9% Euro/Iberian on 23andme. I also get 5%+ Euro categorical admixture on various gedmatch calculators, with different Central-Asian(even Greek, Turkish, and Ashkenazi) categories popping up on some calculators in the mixed-mode oracle setting. Does the "Asia Central" mean Iberian in this case, or is it indicative of something else? Here are my proportions:

66% Asia East (62%-69% range)
27% Polynesia (25%-29% range)
6% Asia Central (<1%-11% range)
<1% Asia South (0%-2% range)
and when I clicked "Show all regions"...
0%-<1% European Jewish
0%-<1% Caucasus
0%-<1% Native American

and the rest nothing
