So the max discrepancy refers to the 360 degree distance, right? And so -0.4481 inches means the mouse movement is off by 0.4481 inches for a 360 turn. This is what makes sense to me. But I have another question, and that's if I can convert this discrepancy into pixels (i.e.: (360 / FOV) * 1920 * 0.030398) And maybe even 1920 * 0.030398. I'm not sure this would be accurate because they're 3D games; I don't know if this math applies at all, and maybe it wouldn't because I'm using Monitor Distance Horizontal 0%. I'm trying to get a "feel" for it or visual how important it would be. I assume the orange numbers means it's not great but I don't know how bad that is in practice (the same for green numbers). Orange numbers make me think the difference is pretty large, but I don't know.
