Yes some of your views are the complications that I face here locally.
By the way, I was refering more specifically to the use of an aimbot, not wallhack.
In Evidence 1, just after the player has crossed the central square in goldrush, if you slow down the scene, you can see in the scene that when he duels with another player at the side of the bank entrance, you can see that the 2nd time they meet after the axis guy jump out behind the wall, this player’s crosshair suddenly accelerates towards the head, faster than his normal swinging speed.
In Evidence 2, he can still achieve headshots while jumping. And he can headshot at least 4 times two newly spawned jumping enemies at a far distance away in two separate occasions.
The rest of the scenes still show him finishing off a kill with a headshot. The same moves for every frag.
Lastly, in Evidence 7, if you notice, this player actually for some unknown reason keeps attacking a further enemy who is not shooting at him in the head. He completely ignores another nearer enemy starts shooting at him. Why is the movement so jerky in this particular scence. He obviously saw the nearer enemy first but why did he had to frag the further enemy?
I hope I had clarified things. Thanks.

do /timescale 0.05 in the Evidence 1 at the part where I mention him crossing the central square.
