Right, you can't take them at face value that's for sure. One thing that has really helped me is that my mom is on GEDmatch too, so I know how she scores. Because she gets South Dutch #1 in populations, I can then look at my 50/50 splits and see that I do indeed get split South Dutch/Hungarian - reinforces the possibility that my father would score Hungarian as his first population. Without this added info from my mother's result, I would have been doing a lot more guessing.
