No. This type of confusion is exactly why I didn’t think the coefficient should even be exposed in the options menu.
I have attempted to clarify how this works in this other thread.
Uniform Soldier Aiming …on or off?
However, it is a complex thing to understand and I get why there is confusion, so TL:DR.
- The coefficient is nota setting that you should match for your aspect ratio. The OP misunderstood its usage.
- USA does not affect vertical and horizontal sensitivities differently, regardless of the coefficient setting.
- The best setting for the majority of people, even of 16:9 screens, is the default value with USA ON.
- If you don’t fully understand why you *should *change the coefficient, then you *shouldn’t *change the coefficient.
