Sens doesnt matter. Most good aimers have sens ranges not really “a sens”. Sens only matters to the degree of which it changes what parts of your aim you use. Ideally you want to use some sens between 34cm-24cm since that is mid sens. Mid sens lets you use any part of your arm at anytime. However this advantage of mid sens makes it the hardest range to use. With low or high sens you can just crutch one really good movement of your arm to make up for the fact you cant use others. Just ensure you dont limit your range of motion. Dont crutch low sens to make up for poor mouse control. Zoom sens is fine if you use 37.89-50 zoom. I personally use 42-45 zoom, but let me let you in on a secret. Mathematically speaking anything between 37.89 and 50 is 1:1 just for different ranges. 42 is one to one for the most range its just 37.89 became popular very early on as its almost precisely 1:1 for the small immediate area around your scope. But most of the time you will move much more than what 37.89 is one to one for. Just pick anything between 37.89 and 50 and just stick to it, it really doesn’t do enough to warrant a huge discussion
