I'm just sharing my experience, nothing else. I use low sensitivities too, and at some point it becomes like you feel like you can even try to do 180 with low sens. Everytime i try low sens at some point it gets to a point where i can make flicks with it. It's not so hard to get used to it. And with that sens the m4 spray becomes perfect, so he just sprayed right near your head as you can see and hitted perfectly, i tbh don't see any suspicious thing going on, but anyway i just gave my opinion from my experience since i have faced it.
