Yeah I would have liked for that to be the case, however I was getting to 250% MDV and I was still unhappy. We might be on the opposite ends of each other if you are REDUCING your values at lower FOVs haha.
Going by feel has worked for me in the past, then I tried to find any calculations that fits the bias of what I configured by "feel".
I kinda wish there was a way for the calculator to work backwards to tell you what the closest calculation is to your manually, in-game configured "feel" sensitivities.
