Yea, I validated the scores on the places I know first-hand. I also spent a lot of time exploring and looking for suspicious gaps like areas without schools (which led to discovering Jedeschule instead of relying on OSM alone).

Finally, I launched an adversarial AI review which created hypotheses based on "common knowledge" like the Schwarzwald being strong in nature, which resulted in a rather long validation script (https://github.com/Ivorforce/wohnortatlas/blob/main/scripts/...).
