Performance rating
Performance rating is a way to measure how well you played in a particular game compared to your usual rating. While you have a standard gameplay rating—in parenthesis next to your username—your actual performance in any given game may be better or worse than this rating suggests.
Game Review estimates your performance in a single game based on the quality of your moves.
In the example above, NM Sam Copeland has a Blitz rating of 2404, but in this particular game, he played at the level of a 2650 rated player (in Blitz). However, this does not mean his overall performance is consistently at a 2600+ level.
How is performance rating calculated?
Performance rating is determined by comparing the quality of your moves to what is expected from a player at your rating level. If you consistently make strong moves above your rating level, your performance rating for that game will be higher than your standard rating. Conversely, if you make mistakes or blunders, your performance rating will be lower.
In the same game, NM Sam Copeland's opponent has a Blitz rating of 2391, but their performance in this specific game was at the level of a 2200-rated player.
Over time, your Performance Rating will average out close to your actual rating. However, in a single game or even a series of games, it can fluctuate significantly, sometimes being much higher or lower than expected.
Why is the bot's performance rating inconsistent?
Performance ratings are harder to assess when there is a large rating gap between opponents. This is especially true in bot games, where players often choose to challenge higher-rated bots to test their skills or compare their play without affecting their actual rating.
Because of this rating disparity, performance ratings in bot games may sometimes seem inconsistent
