I tried converting to Warzone, from Kovaaks.
Resulting sens is ~23-24inches/360 when 15inches was expected. I'm pretty sure this is either user error, or I have some weird setting. WPS is 6, tried locking/unlocking my mouse dpi profiles. Tested dpi analyzers and they both said it's 5% off, so adjusted for that as well. I can actively change my dpi to lets say 1500 and it's closer to 15inches, so it does seem to be reading the correct profile ingame.
I found when I have hipfire and ads to 360, it shows me 15.6inch/360 (which is actually ~24 ingame). When I change to horizontal it reads 24 inches, which is what I seem to get. Not sure if this is related, I noticed destiny2 seemed to have this same issue with the calculation. So I'm pretty sure it's something on my end, but not sure what?
