I did not play well in this game and I got crushed as you can see. Final evaluation +8, I made a mistake and a blunder, and yet chess.com says I played with 92.8% accuracy, and that I played with greater accuracy than my opponent. This makes no sense. How does chess.com calculate accuracy?
They have never revealed how they calculate it.
You did play well in the game apart from that one blunder. Unfortunately, that was a whopper.
And you had 1 "mistake" which seemed much less severe.
So if there were 27 moves, and you have only 2 inaccuracies, then 25/27=92.6%.
You obviously understand that such a simplistic calculation doesn't mean you will win.
When CAPS was rolled out, they used it to judge grandmaster play over a career, not individual games. Now you understand why.
