Do Stronger Players Play More Accurately? I Analyzed 35,000 Games to Find Out

repeated it under different time control, and the trend was always the same—even in bullet form. The only thing that changed was the strength of the growth depending on the pacing, but growth was always there.

This is what I'm curious about - the slope or shape of the curves for different time controls. Overall trend would be upward, but I wonder if there are peaks or valleys around certain ratings that get averaged out.

1.Regarding your first point: yes, the term "precision" refers to the same percentage shown in Lichess’s post-game analysis. It measures how closely a player’s moves align with the best choices suggested by Stockfish. So, to clarify, it's exactly the same accuracy metric used by Lichess, derived directly from the engine’s evaluation.

Could you clarify this point further? Because chess.com and lichess don't use the same accuracy system. So did you stick to solely lichess analysis? If not the chess.com ratings would appear deflated in comparison
