A graph showing the frequency distribution of all non-provisional players ratings would be great. Whilst most of us can only dream of being at the top, it would be really great if we could see where our rating is relative to the medium and mean - better still, let us know what percentile we fit in. This would encourage us to do bettet and keep playing (and keep paying subscriptions).
For the time being, maybe you could use Excel or something similar for your own interest and email me at the same time. Thanks in advance, STANG.
