These are not averages but distances for individual samples (persons).

These populations are heavily admixed, especially in the youngest generation, so the individual result behaves more like an average. Just take a look at the photos and videos.
The generation of people currently in their 50s is essentially the last one that remained largely unmixed.

Additionally, your dataset overrepresents people from cities, whereas the Northern European population has historically been predominantly rural.

Yes I'm aware that my dataset is not perfect, that is why I'm looking also at the surnames data.

According to surnames data Northern Europeans should be around 9.23% of all White Brazilians.
