So I read the "Viewspeed v2 explained" post from Drimzi and tried to calculate what my 360 distance should be if I switch from Overwatch (800 dpi, 8 sens -> 21, 6477 cm for 360) with a 103 fov to fortnite which has a 80 hdeg res fov.
My calcutated distance is 35,862 cm (I used the ready to use formula with a=9/16; x=80; C=21.6477).
After that I used the main Calculator on this site to convert from my Overwatch sensitivity to viewspeed v2 on Fortnite and got a 360 distance of 29.3944 cm for fortnite (hipfire).
So now I am confused why the results are so different. I probably did something wrong in my own calculation but I don't know what. I also don't know which one feels better ingame since I switched just recently from console to pc. But I want to try to have consistent aim settings in different games.
(On a sidenote: What does the base length mean in the "main calculator"?)
