I've made one more change to the ranking algorithm.

For those who don't know, the ranking algorithm is based on the same algorithm Google uses to determine its search results (which is the same algorithm SL is now using when you enter a search query in the "Find All" dialog). The change I made a couple days ago fixed a problem with points leaking out of the system, but it concentrated those points too much with people who had undefeated records. This latest tweak distributes those points evenly among everyone who's played games in the time window (two weeks). This is actually closer to what Google does for their own rankings.
