To have really accurate statistics, we would need a clientmod, each admin has to install and to properly use, so he sets rounds 'officially' live, or resets them, or cancels them. I doubt our admins/referees would go through that.
The native leagues way is via logs, which is more precise as the screenshot method, but fails a lot aswell. (If someone wants to do that, I can change the servermod easily)
And that leaves us to the screenshot method, which someone is willing to make, thanks to Pierre, which is enough to get a glimps of peoples stats.
