Antiban = more client related actions e.g. mouse movement, screen movement etc.
More client actions = more actions to be tracked
= more accuracy in pattern prediction, since there are more samples to be used.
I never use antiban when I am using a private script, but for some reason people are under the false impression that it helps.
It doesn't matter how often you make the script misclick intentionally, or make it move the mouse, or anything related to that. There are specific algorithms on the client to determine the way that the mouse moves and the way that the methods will behave. These are used across any script using any client, making it predictable and deterministic. If there are 10k players playing who move and behave in the same fashion, eg. Move the mouse the same way, it is obvious they are using a script.
Tldr: antiban is pointless, if jagex wants to ban you they will.
