alanback: Well, using the example of a tournament, if I want to play in a tournament with all people who have a similar BKR as myself, maybe because the game has a high luck value, so I make it for only people with a BKR over 2200, then the game goes on for a year and some guy beats me but they now have a 1800 BKR, does that make sense to use their 1800 BKR instead of the one we both started with?


Okay, how about with ponds then? I sign up for a large pond with 200 people and my BKR is 1900. My computer goes down and I miss the first round and come in last place. In the mean time my BKR rises to 2400 by the time this other game finally ends, and then I am killed because now I have lost to everyone else, most of whom have a lower BKR now than mine!

Shouldnt at least in ponds the rating be calculated at the time you actually lose, rather than when the thing finally ends?
