Star Wars Battlefront 2 FOV seems strange

I am trying to match my Battlefront 2 FOV to Overwatch's 103 Horizontal FOV. In the Config file the FOV seems to be in Vrad, so I used the value of 1.231029598 rad in the calculator, which showed up as 70.53 V degrees and 103 H degrees. However after opening Battlefront 2 the in game menu showed my V FOV to be 68 rather than 71 or 70 degrees. Is the config FOV not actually in Vrad? If so how can I enter a more precise FOV?

Nobody replied but in case anyone else is wondering, I think I've figured it out. I set my FOV to the minimum VFOV SWBF2 allows which is 44, which gave a value of 0.8 in the config. The the maximum value of 110 degrees gives 2.0 in the config. 44 degrees in radians is

0.767944871

110 degrees in radians is 

1.919862177

0.8/0.767944871 = 1.041741446 = 2/1.919862177

This means SWBF2 config multiplies the actual VFOV in radians by 1.041741446. When inputting 1.231029598 into the config the actual FOV was 1.231029598/1.041741446, which became 67.7 in degrees and was displayed as 68 in the game.
