A very quick comparison between this script, normal recoil and SealTeamSix Profile using "No recoil by SushiWang 2" (First Pic)
Also, found that this script may not work for every gun with 11 sensitivity like OP says, as it drives your aim to the left.(Blackbeard pic)
Use around 24 and 25 sensitivity on all 3 since 11 is like normal recoil.(Blackbeard pic)
I set the values in this order: 24, 24, 25. (Blackbeard pic)
---Update
Also I found that this script doesnt work well on all weapons, for example Thermite's assault rifle and the type 89 (the last one's a bitch, but it actually works worse than SealTeamSix no recoil)
