Yay, that is the best benefit. Plus, I feel better about owning land now.

My test results were very similar. One estimate put me at 99.1% European and another estimate put me at 98.5% european, with 1% African and .5% native. I told my older family members about it and if they want to believe we are native and african that is up to them. I tell people I am completely european descended as I have no proof to believe otherwise.
I don't see where they make that claim (3% margin of error) anymore. Their analysis has become much more precise. African and Native American DNA are very distinctive, and even in tiny blocks they are likely real. Both are commonly seen in Americans with colonial ancestry, reflecting the mixing of races that occurred before it was outlawed (and obviously after as well). I have distant African and Native American ancestry and both are reflected in my 23andMe results at about 1.3% each. Many people who believe they are "completely European" have found out otherwise. And many who believe they have native ancestry are disappointed to find out they don't, or that it did not survive the generations in their DNA.

Most people I know are mixed somehow. In my city a person can look white, black, Mexican, etc, and have a parent or grandparent that isn't. It's very common. Lots of white Americans claim to have some Indian blood, a study I heard about said most black Americans have some European ancestry, while 30% of white Americans have some black ancestry.

I don't think any individual is one hundred percent anything... just a mixture of genes. I guess a person can be considered one hundred percent human... but according to the theory of evolution, all life descended from bacteria-like microorganisms.

I'm sorry but .1% has to be well within the range of error. It's quite possible you have no native blood at all. Not to mention i believe all humans are about 99.9% genetically identical with that .1% representing the minor racial differences.

Frankly it could be argued that anybody on earth could share .1% genetic similarity with any ethnic group.

You misunderstand how these tests work. They are looking only at those parts of the genome where people can differ that are useful genealogically, so they are not looking at the genes that all humans have in common.

And, they can now pick up even a tiny segment of DNA within these regions that are identifiable by race. So if you have a very small DNA segment that is Native American they can detect it. And it may account for only .1% of your total DNA.

Makes sense to me. If they can find one gene mutation that originated in North America, and nowhere else, then that would seem to be fairly conclusive.

0.1% is just noise

4 grandparents
8 great grandparents
16 etc
32
64
128
256
512
1,024 (the American Indian would be one of these)

At 30 years per generation that would be over 300 years. My parents were both from Massachusetts with relatives up through eastern Canada. Hopefully, I can identify the specific tribe somehow.
So in eastern Canada if 98% of the new arrivals were men, and the 2% female that showed up were nuns, how come we ended up with all these babies? I think you've just come up with the answer.

Just a note, your racial percentage and DNA inheritance (autosomally with alleles), does not work the same way. You inherit 50/50 from parents but due to recombination and DNA's own will, you can inherit from 1 parent anywhere from 0%-50%. However, once you get back to a 4th great grandparent, you have the chance of not inheriting anything and there is very little chance you would NOT inherit anything from a grandparent or great grandparent.
You can be 1/8 Native American which is 1 great grandparent and is 12.5 of that grandparent's ancestry. On a DNA test (23) you can inherit 2% to as high as 6% of their DNA. Percentages can even vary with siblings.

Now, the parameters of 23andMe are about 7 generations which is a 5th great grandparent and 1 Native American 5th great grandparent is 1/248 of your ancestry. Anything beyond this is a crap shoot.
Small percetnages are not necessarily unreal, however they are small and anything under 1% can be noise. Once you get to a 5th great grandparent DNA of ancestry those segments tends to fall off the genome by then if no other introduction of that ancestry enters your genealogy. Very rarely do they hang on past 7 generations.

"1,024 (the American Indian would be one of these)"

This is very far back. 0.1 is 10th of a percent and starting at your parents counting back the first generation, 1024ths would be 8 generations back. Because this small percentage showed you would be inclined to think it is from this ancestor back 8 gens., however, I think it is too far back to show on a DNA test. I think maybe this is noise, noise tends to be about 0.1. Very common number. Some Europeans show 0.1 East Asian.

Your best bet if possible is to test the parent from which you believe this came. Or maybe send to Doug McDonald for analysis. You can find his email on the 23andMe forums.
