With good movement reading (see below of my strafe aim guide for a definition), you don't even need to move the mouse that much or to be reactive to hit a lot, as shown by this video. I'm moving the mouse almost at all times btw, it's not just mirroring.
Note that there is one place where sensitivity randomizer is helpful, and it's precisely in these "dodge" scenarios. This makes mirroring much harder. Even then, it is preferable to have a target moving slightly faster than you rather than using a sens randomizer (slightly slower is bad, beause you can cheese too much with movement). This is why you should ALSO grind movement scenarios in aim trainers. Unless you want to be max rank in aim trainers and hard stuck plat in a real game like so many of these otp.
By movement reading, I mean the intuition of where you should place your crosshair based on the apparent motion of your target on your monitor (which depends of both the target's absolute movement and your own). This is pretty much based on understanding the possible "angles" a target can take. This of course depends on whether you are using a diagonal direction, whether your target is using a diagonal direction, or if both of you (or none of you) are doing so. The concept of "angling" in the lg duel scene is closely related
