It is supposed to make a difference but I am not sure that it ever does. What is does effect though is the count for wins, losses and draws. Someone like Dano takes some pride in being over 80% wins.
Some info on BKRs can be found here. The formula is supposed to be:
new BKR = ((old_BKR*Number of Games Played)+ OpponentsBKR + x)/(Number of Games played + 1) where x = +400 for a win / 0 for a draw / -400 for a loss with a failsafe to ensure that winning against a much lower opponent does not decrease BKR. Hope that helps.
