[...] That shouldn't be a pickup log though, maybe it got pickup up because of TF2Pickup.net in the name? Our log names are like these http://logs.tf/1002413

Do you have an idea how I can have stats for demo in tf2pickup when I can tell for sure that I never played a single pickup in my life? ;o

@GentlemanJon not a complaint about your system at all. That sort of limitations is unavoidable. I think a lot of people play lobbies "for the logs" regardless of how the player ranking works anyway, because winning a lobby doesn't matter to most players. I think only the newer players who are learning to play comp in tf2center really care about winning their games. And I've noticed sometimes it's good to be on the losing team of a lobby if you're playing against prem players or whatever. Your team might be getting roflstomped but if you hold your own well you often go up in the rankings, whereas if you're in the team that's stomping but not doing much you can go down. So yeah I don't avoid playing against the Mikes of this world, idk what the others think about it though.

Examples of good teamplay like bodyblocking (or airblasting) an uber to save your combo or causing a distraction for your spy to get a big pick are things that can't really be quantified in an algorithm.

[...] A transparent system where you know what you have to do to advance in rank could not only make people play more seriously, but also help people improve if implemented in a good way.

though a lot of people might start trying harder instead of messing about if they know that if they throw and lose their rating will go down.

It's not a teaching tool, just faceless useless blind judgement. The only really useful bit is if you like to keep track of your stats, but that breaks sometimes too. edit: I think a win/loss system would work in showing quality, but it would also have knock on effects - players would develop negative habits trying to game the system, leaving queues to protect their rank, etc. You need completely anonymous joining to do something like that.
