You can't judge anyone's skill just by rating. Rating is more about raping less skilled players whereas etpro is playing against people which are as good as you. ETpro is also more than just aiming, you gotta be able to work as a team and have some gamesense. Skill is a summary of these three (aim, teamplay and gamesense) factors. But by judging the top 25 players' aim I could say they are low/+/med- (remember they even might be low- if they can't work as a team at all or don't have any gamesense on ETpro)
