From my testing, the ADS always lower than the actual sensetivity. Correct me if I am wrong, but its supposed to be the same on every weapon? (I made a bind for every gun group and tested everything indivudally.)
From what I remember, my rust sens was something around 0.21 and the ADS sense I got was something like 0.98 (Yes I have set it as ADS Sens, not as the normal one) After some testing, I managed to get my bow ADS the same as my mouse sens, which was around 0.119. Perhaps they changed the ADS sens again with the weird crosshair system and weapon overhaul?
