I just saw this game, where played by 1000+ rated players , with 1 mistake , 7 blunders ? And the accuracy of white player is still 95+.

How do you guys calculate those stats?
I agree that results like that make CAPS seem like a joke.

In a game that has a lot of easier to find moves (maybe forced moves, simple endgames, etc) accuracy can get pretty high, even if the early game has more inaccuracies.
I was actually just literally discussing with out team about an upcoming article we are going to post about how accuracy is calculated.
sounds like CAPS is bad. This is a shame, since I thought that that system declared that Carlsen was the most accurate and therefore best player of all time.
Accuracy is not equivalent to CAPs. In Chess.com, "accuracy" refers to the % of moves that you played that were in say the top 3 best moves recommended by the engine. So you could play a lot of moves that were not the best move and still have a high precision score. If you want to see how often you played the best move, go to to the "details" tab for a better measure of your playing ability. For example, I just played a friend and we both scored 96% CAPs but we both had a best move rate around 55%. Also, I've noticed when a stronger player is playing a weaker player, the stronger player's precision score is much higher. Chess.com may also compare the precision between both players throughout the game before showing the final precision score. Not sure

Site CEO Erik said accuracy was a new name for CAPS when they rolled out the new analysis.
They haven't given any specifics about how accuracy/caps is calculated. They are both the same.
The CAPS score ceased to be relevant when they rolled in the new, inferior analysis board.

Accuracy, or precision? You shouldn't use those words interchangeably as they are different. In other words, you should be more precise with your language. 😄

I was actually just literally discussing with out team about an upcoming article we are going to post about how accuracy is calculated.
Is that article still in the works? I would really like to better understand the accuracy scores too. For example, how is it possible for the following moves to be considered 98.1% accurate?

CAPS became useless when they changed the analysis. Since the analysis is also useless, look elsewhere for a report.
Looking into this 98.1. But the fact that you had 17 out of 23 moves perfect, that is VERY strong.
can you say 'database' ....?

17/23=73.9%, !!
