"Cope" is not a measure of excellence. It's an excuse. Agreed. Syphoning off the worst behaving 1000 might do a lot for the other 9000 though. But, until that happens: And why is that a bad thing? (In the absence of being able to separate out the bottom 1000?) Why? What good does it do the brightest to be denied the best opportunity for them simply because of your idea of "fair"? Should we cut off Usain Bolt's legs so the 100m is fair for the rest of us?
