OK thanks, setting my fov to 1 does correctly give me the correct value for a hipfire 34.6cm/360, but now I think the zoom sensitivity is wrong, at least for sniper it's too high (It gives me 1.25 which is impossible and 1.00 already feels too fast). The value it gives when I leave the FOV empty, 0.89, is much closer to how I think it should be.
