Hardly. Raider.IO has helped so many runs it's not even funny at this point. Every time I take a chance on a lower rio player, it seems that their score is very, very correct. 99% of the time they turn out to be so stupid it's surprising they can even read.
Of course, that's not to say every player with decent rio is an actually decent player. However it's an order of magnitute more likely for the lower rio player to be retarded. And don't do the "but I have 67891 kids, 2871 wives and 120 mothers in-law. I have no time to play!" You don't need infinite time to get a slightly better than average rio. You can push your own key. It's not an excuse.
