8 years ago First I need to clean my house WRT data storage. There's currently no notion of time, so no way to implement the "decay after a week" logic.
Ideally I'd have a solution that allows me to go back in time and apply alternative rating schemes from the start.

As a ping-pong channel rated player I want rated players who don't play to lose their rating So that inactive players are encouraged to play, or unrate themselves
