You are using 360 distance to matchHipfire, and the 360 distance does not change when you change FOV for these games.
However, ADS and scopes are matched using MDV 0%, which is affected by the FOV change.
ah, yes. it's matching your aim sensitivity to your old fov. it does that- sometimes you gotta re-enter it with the converted sens in the top column to figure out what the new fov's sensitivity would be.
