With highscore I ment: http://md-ladder.cloudapp.net/allplayers
Do you mean you want to see something different on that page?
Would just be nice to have a column of clan icons and being able to sort players by that. Always nice to know which player belongs to which clan and rate clan activity (e.g. for those who are searching).
Or do you calculate new elo based on the not expired games (which would effect lots of other players)?
Yes. Every 2 hours, I recalculate Elo based on unexpired games from scratch(assuming everyone is rated 1500).
I am no expert of the elo-system, but this may result in the following:
automatism: players tend towards 1500 elo
a) I need to play a lot of games to get a high elo.
b) Players, who do not play a lot of games, may not be rated accurate.
At the one hand a) makes sure, only active players are ranked high. On the other hand activity may substitute skill-level in some way. Not sure how big this effect is, but it may depend on how big the player pool is.
No big problem right now, but a thing one should observe in the future. It also may take some time until the system is really balanced (as all started with 1500 elo).
