1st of all, cheat o meter 5% is nothing, it proves absolutely nothing. I know guys with 25% and they are 100% legit.
2nd his SPM suddenly spiked from what lvl to what ? Pay attention on numbers. If it was from 300 to 1200 then yes i see your concern, at the moment i dont. SPM jumps up tnx to medals, see report: http://bf3stats.com/report/pc/89360927#AzGuuRR
The guy playes purely the objective and punkbuster didnt catch him so far. He has no damage hack.
