Smoothing
Also called: Smoothness
How gradually an aimbot moves your aim. High smoothing drifts onto targets like a human; low smoothing snaps instantly.
Smoothing controls how quickly the aimbot moves your crosshair to a target. With high smoothing the aim glides over several frames, like a player tracking. With low or no smoothing it jumps there instantly, which is the classic "snap" that gets clipped and reported.
Smoothing is the single most important setting for looking legit. Start high and lower it slowly until it feels useful, not the other way round.
Some cheats let you set smoothing per weapon (Fortnite Private does), so shotguns can be faster than rifles.
