I want to know what it is, I have no idea where to search for it myself so I'll ask here.

Oh and also the calculator for said games accounts for 4 (Shadow of Chernobyl and Clear Sky) and 8 (Call of Pripyat) decimal places, in practice the games round up sensitivity decimal places to a maximum of 5.

Could also leave a note that your sensitivity is reduced by the "control_inertion_factor" of a weapon for hip fire, and "crosshair_inertion" for ADS. Your knife, bolt, binoculars, empty hands and pistols have a control_inertion_factor of 1.0, making your hip fire sensitivity exactly what you set it to, for the pistols and binoculars the crosshair_inertion differs, probably to simulate the weight of each gun. 

A value over 1.0 lowers your sensitivity and under 1.0 makes it faster, 1.1 being 10% slower and 0.9, 10% faster for example.

Also the scope_zoom_factor is the FOV change when ADS-ing, 90 being no zoom, 22.5 being a 4x zoom for example.

These games do not use a pitch/yaw value like CSGO etc. You can find a close approximation, but that's not how the game actually calculates the sensitivity.

I've fixed the rounding issue

Thanks for fixing the rounding, I often change my sens when I suck at multiplayer or for whatever reason feel that my sens is off, I did this a lot with Clear Sky and recently Call of Pripyat, surprisingly the multiplayer still works, although I had to get a .dll and a cd key off some russian sites to enjoy the Call of Pripyat multiplayer, for some reason I'm also cucked by the game not wanting to download files from a multiplayer server because it's on a different version than the last official one, limiting me to essentially 2 servers with 2 people playing on 1 of them most of the time. Maybe it's the annoyance of having to get that dll off the said russian site that makes this game so dead, such a shame.

 

Found the values myself in the end,

1.145915646284487883135702673087 - for Shadow of Chernobyl and Clear Sky;

1.0417414212593959288745257182807 - for Call of Pripyat.
