also first thing that crossed my mind!

very interesting project! I'm a chess aficionado and playing vs stockfish does always feel a bit clunky at ~1,700-1,900 ELO. How are the 100-point buckets calibrated? Would the ~1,800 ELO truly win ~50% of the times against humans with a similar rating?

very cool idea! Like others have said, "country" doesn't feel like the right level of aggregation. Municipality, street, or even coffee shop itself would feel more natural, although there's a sure trade-off with the effort to source the data
