Chess.com has a feature where people can see a players estimated elo based on how they played one game. I am not quite sure how it is done, since a higher accuracy doesn't necessarily mean a higher rating estimation. Does lichess have something like this? If not it would be something cool to add.
I attached one of my games and one of Magnus's games so people can see what I mean.
