This may be asking allot, but it'd be nice to get more from this. A few things that would be cool if tracked to show more raw data:
Amount of public servers 0 through 1/4 full
Amount of public servers 1/4 full through 1/2 full.
Amount of public servers 1/2 through 3/4 full.
Amount of public servers 3/4 full through filled.
Amount of private servers.
Amount of dedicated servers.
This would be more complicated, but if done would show were most people are at any given time.
