Yes, the DPM in the logs are definitely doubled as Max pointed out. But the accuracy is very suspicious unless bugged also, he's a hacker.
Did a little search and this guy has been banned for hacking on a dodgeball server. Auto reflect maybe?
I kind of doubt the log glitched for the accuracy, as he has retarded accuracy in some other logs:
http://logs.tf/1185555?highlight=76561198138359211 92% sniper, 95% scatter.
http://logs.tf/1185532?highlight=76561198138359211 66% sniper, 95% scatter
I didn't bother looking for more than the top dozen logs to find these full on retard accuracy stats this kid is getting.
Yea he is cheating. But someone humor us with some demos please
