As far as I know the worst loss is the loswest rating of the player you lost to.
I don't agree with tracking timeouts for winners. The reason they are tracked for those who incur them is to identify those people as being less polite (and certainly less reliable). This allows people to set up tournaments and to block people with high time-out rates (because it would spoil the tournament if such people entered and then just lost interest). However, for winners a win is a win. Imagine you had played an opponent and after 40 moves of driving him into the ground he just timed out. It would be frustrating to have such a win taken away from you. By including it, your rating is not being inflated. When someone time outs it is tantamount to resigning (but simply less polite).
What is a Glicko RD?
How is "worst loss" determined? I have had some bad losses but they never appear as my worst on the stats.
Where did the 30,000 accounts come from? I thought the database was cleaned up with 15,000 active accounts.
Shouldn't a stat be added for wins by timeout? We track losses because they apply to the individual but aren't we inflating our stats for those wins too?
Rather than a pie graph for the graphical description, I think I'd prefer a bar consistent with the Game Explorer and a link to game explorer below it to analyse the games.
