ADS Scaling

I have noticed that the ADS setting in the game is not correct. The default setting is 1.0, which should correspond to the same radius without ADS. In order for the sensitivity to be 1:1, 1.3 must be set.

I tested this with deactivated mouse acceleration as follows:
I stand at a certain position in the shooting range and aim at a certain point. Now I move my mouse from the right to the left edge of my mouse pad and memorize the end position. I do this three times, as this method is subject to small deviations. I now do the same while aiming.

ADS 1.0 therefore corresponds more to the value 0.7.
