I have updated the East European map and added a new shade for over 80%. But without knowing where the Polish samples come from, it's hard to figure out the boundary between the 60-70%, 70-80% and >80%.
Thanks, Maciamo! I am sorry I post it so late. Here are my matches from some European countries with 4 grandparents from their country:
