You will have to show me that part where a set amount of Native American was set when trump made his bet with Warren. Got that for us?
Don't think you're understanding statistical processes and the "confidence" values of the data. It's pure crap.
A confidence range of 1/64th to 1024th means it's NOISE. THERE IS NO MEASUREMENT.
Moreover -- a university and academics need permission to use the LARGER group bases for ethnicity, race, origin that they've invested $mill into -- and this hired white coat did not use them. He put together his OWN "group references" for CUSTOM STUDY that he was urged to do to PROVE her case.
If she wanted accuracy and less variance in the confidence, she should have just gone to the commercial testing sites.
In HER favor --- the commercial sites go ALL OVER THE WORLD to build their reference "group bases".. It's a HUGE investment. But the most difficult samples are from Native Americans. There is little cooperation in supplying their ancestral DNA because a lot of them fear EXPULSION from the tribe.
Since the casinos opened and they became "Big Gambling", there's been a lot of roudy confrontations about belonging to a particular tribe. And very FEW of them want to have their tribal association testing with DNA techniques.
