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?

The 100-point buckets are fine-tuned on blitz games from users at that Lichess rating. Lichess ratings tend to be a bit high compared to FIDE/USDF/chess.com ratings. There's a good post at https://chessgoals.com/rating-comparison/ comparing them
