Because its not 21% from your base value. You need decrease new value for 21% to reach your target sensitivity. I mean 0.192911 * 0.79 = 0.1524.

It looks different becouse in your case eyecup is installed on scope. I think this is game bug because the eyecup should remove the image outside the scope. The most of players use pso without eyecup.

Hello. I have some doubts about the FOV in the PSO sights. In calculator we can see, that PSO 1 have VFOV is 9 degrees, and PSO 1M2-1 is 11 degrees. I made some tests to apporve this. My test setup was based on AK-74N. Test method was to find some object that length can be easily measured in noscope mod and sequently with PSO 1, PSO 1M2 and PSO 1M2-1 scopes. I choose one door on the customs map and stay in same distance to it. The test was completed for both 50 and 75 ingame FOV. Using screenshots, made during test, i create two pictures, that were measured in the ImageJ program. Based on the measurement, the scope magnification was found as (length in scope / lenght in noscope). It was found that all tested scopes have the same zoom magnification is about 5.589x @ 50 FOV and 9.052x @ 75 FOV. Then i calculated the VFOV of PSO scopes by using this formula: scope VFOV = 2*arctg(tg(FOV/2)/MAG). The results is 9.53864 degree @ 50 FOV and 9.69062 degree @ 75 FOV. Is that error in calculator, or i have made some mistake in tests?
