I'm curious because in playing some other games that have detailed 3rd party stat trackers, a lot of users I thought were for sure smurfs actually weren't.
Like someone in the match would have a 50% headshot rate, but their career or season average was like 7%. It looked like they were just having a really lucky game. With 10 or 12 players, it doesn't seem crazy that a good portion of games have 1 player who's just playing a better game than they normally do.
