I can distinguish them without difficulty and I'm sure can plenty of others. on the other hand, if your memory ain't what it used to be .....
Naa, you're fooling yourself
If you want, I'll download 40 games of players 400 to 700 points below your rating. I'm sure you'd be able to tell high and low, but separating them into 4 categories correctly would be fairly impossible. You certainly wouldn't do it "without difficulty."
I guess we'd have to add another 15 games of players not in that category to keep you on your toes. I.e. players only -200 or -300, and also players below 1000.
Oui. Sounds more like crotch tho ...
