Use a calculator you rarely use on GEDMatch to compare your results to someone else in your family or someone else that you know has a similar background to you. This is just for fun, of course.

I’m using puntDNAL K12 modern for my maternal grandma’s results and for my results.

Takeaway:
Doing this reminds me of why I do not use this calculator for my background. Through my grandmother’s side of the family (which is hard to research on her father’s side since her dad was an immigrant from Croatia), I’m Croatian, English, Irish, Polish, and Scottish. Through other sides of the family, I’m English, French, German, Irish, and Norwegian. This is all within the past 4 generations, and I can’t trace some of my USA lines outside of the country yet.
