Gambled FOV, who can calculate this setup?

I have a curios setup,im new into fov calculation, or i simple dont know not really anything about it or what im doing.
I have 2 Screens
Nr.1 Acer Predator XB241H 24 inch @1080p
Nr.2 Philips u28d590d is 28 inch but with custom res. of 2200*1080
no g-sync on at both.

on that i supersample it with SRWE to 5760*1080
on that i have

Distance from Screens Set to:770mm
Screen Width is set to: 1535mm

Camera Distance is set to 17.0 (FOV is Greyed out at 10°) i dont know why its actually locked but it works i think and pitch if it matter of -3,6° and height is 3.0
Game Resolution is 1920*1080 in windowed mode at 100% scale
and the triple monitor setup is enabled

at this site it says i have now about 26.5

this setup works not well cause something is in conflict with the virtual mirror and has to be resetet every new start but uhhhm, it changed at last and worked the whole process of what s the fov i like.

This setup is actually no joke, i played a couple of rounds and i like it, it feels pretty natural to me cause all other stuff like controller vibration and RHMACC makes it a hell of a lot fun to me and im felling like im actually in the car cause vibrations are really good and the car setup feels like im glued to the ground.

So does anybody know what i could improve.Dont take it to serious.
Maybe i forget this game in a few days or weeks.
