Showing the user's highest rating

I like the idea :)

Done! Go to your profile and click on rating. There are still some problems with Gomoku ratings, we may fix it in a few days. Showing Sudoku ratings is a more complicated story - it will take some time. NB! If the graph does not show the correct rating in any other game (besides Gomoku / Rendzu), be sure to let us know!

still doesn't show the highest rating when I was in Vind :), I remember that I was once green in chess, but it's not reflected in this display. It should be that the highest is written separately and then the current time period, which is currently visible. (Because if interested people look, they would get an idea of your development.)

We had a rating reform in the meantime. So the post-reform rating is shown.

right, yes, it was

Gomokus gives much more than I deserve

Yes, the gomoku rating chart is really wrong, but hopefully it will be fixed soon...
