8 screens, 4 kills
Blackout was kind enough to donate some demos. He uses mouse accel, has a 144hz monitor, pings roughly the same as gizmo. And this was a 44acc duku game.

blackout kill on spyzy: ^^^^^^^^^^^^

blackout 180 double take. ^^^^^^^^
pretty good example of someone using mouse acceleration in a more familiar manner.

Blackouts GIF. large sample most shots taken in succession^^^^^
84 kills, roughly 10-15 on the edge of the visible model or off of it, about 3 of them hit in a sweeping manner. Nothing really comparable to Gizmo. Even the shots near the edge of the visible model are totally different in regards to speed and where the crosshair comes from. The man sometimes sweeps but rarely starts near the model and ends at some far off place.

Gizmo GIF. not necessarily taken in succession^^^^^^
45 instances of sweep, the precision and speed while using an aiming style best described as flailing is unbelievable.

Just a couple more sweeps from nitro. There'd be more but I hadn't started documenting things as thoroughly as I have been doing lately.
here's another blackout gif and a youtube of the entire sequence
The kind of shot you'd expect to see a veteran of the game make, hitting near the center rather than on the edge of the model.
blackout ultrakill
another blackout ultra kill, still not seeing anything remotely close to the kind of shit gizmo pulls off regularly.
I asked and got blown off twice when inquiring about the hitbox tool or whatever the admins use to determine where hit boxes are in demos. So I'll just keep making gifs that give an approximate location that no human is going to routinely hit with mechanical precision anyways.
