Some GameKnot statistics
===================
- Red curve: There is a strong correlation between rating and premium membership. But also at the low end of the rating scale there are more premium members.
- Blue curve: The raised levels in the 1100-1300 rating range are probably due to the influx of new players.
- Orange curve: Look at when these active players registered at GK. You can infer the growth of GK from this curve. Notice that joining is more popular in the winter months. The drop-off at the end is because many newly registered players are not included yet, they need some time to reach 20 games.
