nabla: This is a very interesting discussion. I have recently felt that my BKR quite exaggerates my actual skill. Have usually have trouble with players rated above 2250 yet my rating has grown to >2300. I try to play multi-point matches with most players but often end up playing games with much lower ranked players (2000 - 2200). These games boost my BKR over time even though I'm not playing any better. Losses against similarly ranked player don't decrease my BKR significantly and so, my ranking continues to grow.
