This type of cheater with AimLock program, whose mechanism is related to fps, is easy to find when you have more monitor hertz than the cheater, their aiming looks like a step-by-step movement towards the target.
Another game code example is W2JSVA. Where the RUSHR player shoots merci from 03:01 to 03:04, and when his sight is near the enemy model, this micro click is visible with the same time pauses. I can clearly see in 360fps how his scope just skips frames and has pauses. You can also see this on the 0.25 replay. It looks like it’s just AimLock, which is related to its 144 frames.
It seems to me that the developers should introduce the recognition of this Aimlock mechanism into their anti-cheat system. Seems like a pretty literal and doable task.
