I agree that the 16:10 appropriate FOV is close to 100.
Im using a 1920x1200 (24 inches) monitor, and the game looks better around FOV 95, I guess FOV 100 is correct for 27 inches.
in game I have to set 90 FOV and then adjust the fov pressing the FOV´s key and using the vertical mouse axis.
This method is not precise and is very annoying that I have to do this every time that the game is started.
I miss a method to set my desired FOV by default
