So i always try to match the fov in the games, or "upscale" it depending on what i deem necessary, matching the pixel ratio is how i've been doing it, does that actually mean the real sensitivity will be matching?      
The matching pixel ratio can't be clearly shown, because the moment i increase the sensitivity it already changes, but coming back to the question, is what i said before actually correct?

Matching pixel ratio is the same as Monitor Distance 0%. This keeps the tracking speed consistent between FOV's.
