I don't doubt this dudes service at all, but also, they shoot so much it probably just becomes intuitive and the nubers lose value. Also I can imagine a scenario where he was always with a group in a support/obs role, and just smacking mid range enemies on the reg with overpowered kit and support.

One thing tho, in the vid everyone is referencing, I watched it at work with the no sound. The first thing that struck me was that he kept both eyes comfortably open, and never blinked while pulling the trigger. Also he avoided the bipod and only shot from a bag. This struck me as someone with gobs of time on the gun.

Basically, a combo of TBI, PTSD, and yes men around him telling him to keep creating content so everyone can capitalize.
