Apart from the private games and all that:
What excactly does this graph show?
The x-axis is clock-times.
The y-axis is "games started" and peaks at 24000. One way to read this graph would be that every day at 20:00 'o clock 24000 matches are played. That is clearly not the case, so what does it actually show?
Is it summed up games over many years? (Like a histogram?)
