The authors used the program Crafty and argued that even a lower-ranked program (Elo around 2700) could identify good players. [19] In their follow-up study, they used Rybka 3 to estimate chess player ratings. [20] In 2017, Jean-Marc Alliot compared players using Stockfish 6 with an ELO rating around 3300, well above top human players. [21]

Although a player might perform significantly better or worse from one game to the next, Elo assumed that the mean value of the performances of any given player changes only slowly over time.
Performance rating (abbreviated as Rp) in chess is the level a player performed at in a tournament or match based on the number of games played, their total score in those games, and the Elo ratings of their opponents. It is the Elo rating a player would have if their performance resulted in no net rating change.
