Aiming sensitivities are too broad

I play on Xbox. I use the “Steady” response curve for a balance of fast aim and good recoil control. Plus, it’s the only one that doesn’t drift on its own. I use 5 sensitivity for everything except the 1x optic (4) and the 6x optic 👿. It’s still a little slow for me for higher zoom optics, and the 1x optic. The high zoom optics, 5 is just a little bit too slow and 6 is way too fast. There should be a decimal system for sensitivities, or at least be more than 8 numbers to the sensitivity system. It really screws me up a lot, and I’m sure there’s a lot of players just like me who are frustrated at their sensitivities.
