Uniform soldier aiming not working correctly

In BF 2042 when i set the coefficient for uniform soldier aiming at 178 for my 16:9 monitor the cm i moved my mouse on my mousepad to move my crosshair from the center of the screen to the the edge was always the same independent of the fov or the scope.

i think this is how usa should work.

In BF 6 the coefficient seems to be wrong. All scopes with different zoom levels need different cm on the mousepad to move the crosshair form the center to the edge of the screen. i tried 178,133,0 and a lot more coefficients without a positive result. 

i play on xbox series x with native mouse and keyboard.
