I think it would be fair if we could see what criteria the game creator has set for waiting games.
A good example would be currectly IMupChucKing and zockerdotcom have got heaps of backgammon games visible in the waiting room to those who are a higher rank than them (ie if they lose, their rating goes down very little but if they win their rating goes UP a lot more. RISK LITTLE GAIN MUCH)
I remember a time on yahoo where we only used to play those who had a greater than 40% down games for instance. That is, they play at least 40% of their games against lower ratings.
Currently on this site there is no way to tell that and hence players such as those mentioned above can simply play as many UP games as they want and of course their BKR will skyrocket.

Lets get it fair and show the up-down stats.

I am in no way at all suggesting IMupChucKing and zockerdotcom are doing anything wrong. ON the contrary, they are being very smart in the way they are trying to achieve a higher rating.
