I the green graph in the players profile showing the 300 last games, I think there is too much green.
I think that the vertical scale should reach from the minimum rating of the 300 last games, rather than the minimum rating of all the players games.
For example - look at the graph of User 51824
. It is almost flat but the most of the green reaches all from 1190. It's way too much green in my taste.
But it's only a minor problem though...
