I've noticed that when selecting the apex sensitivity in kovaak's, 110 doesn't correspond to the value for 110 in apex itself? This calculator seems to say that the value I'm looking for in kovaaks is 108.5 (to match to 110 in apex), is this correct? This would seem to indicate that kovaaks slider for FOV corresponds to Hdeg 4:3 instead of apex's in game FOV. Can someone please confirm all this?
Also, slightly off topic, but is there a way to actually measure FOV in games so that I could answer this type of thing myself?
