Here is where stats are shown: PsychoStats

But you're missing the picture... no one cares about your rank/KDR/kills with a certain gun/how many times you won an escape map. You won't win anyone's affection or admiration because you can run through voodoo island 90% of the time. It's merely a way to show your progress, for your own benefit, not to wave it around like it actually means something to others. My advice: Live in the moment, enjoy wins/kills when you get them, and if you're gonna go out; go out with a bang
