Having now VTFV (viewed the friggin’ video), I’d like to add that “statistical noise” is a real term, but it’s when a fraction of a percent of other admixture appears but there’s no outside proof that it’s real: 0.1-0.3%, usually. Certain ethnicities can sometimes seem like others, autosomally speaking. 16% is NOT statistical noise. It’s a great-grandparent or closer.
