I'm not a member so I can't analyze and see the accuracy of all my games, so how do I calculate it? I can see from the games I can analyze the that it's not just the ratio of brilliant moves, best moves, excellent moves, and good moves to inaccuracies, and blunders. Does anybody know?

Go to your game, and if you are on iPhone/iPad, click the middle button on the bottom thing (the analysis one), then you have two options. Game analysis and self analysis. You can only do one game analysis each day if you didn’t pay for anything, but you can do unlimited self analysis I believe. In the self analysis section there are multiple options to analyze your game.

I don’t know exactly how to get there if you’re on computer.
