I agree about the coefficient usage, that's why I didn't change it, but I wanted to do this "test" and it surprised me how well I was performing with 177% coefficient. Probably I should have used a lower magnification, that's true, but it's also true that hitting a bigger target is easier and for some reason considering how aggressive I play it ended working out very well for many games, and I had no problems adapting to the new sensitivity, I didn't expect that and I even considered switching coefficient, but I didn't want to ruin my muscle memory, that's the reason of my post basically
Probably I should simply adjust my fov a bit and use lower magnification, I guess
