i think the best sensitivity is the sensitivity fully using the length of your mousepad
for example
you have a 48cm zowie g-sr mouse pad,
and the minimum fov game you play is pubg which is 80 fov in tpp hipfire
you should your pubg sens 48cm/360
that would be 51.503047/400dpi in game
and then find a X% monitor matching to find the consistent sens for higher fov game,90 fov csgo edpi 800+,103 fov overwatch edpi 4000+,120 fov r6 20cm/360
which is very similar to the pro sens
but considering the weapon in pubg has recoil,i think 0%mm is not good for controlling auto mode akm
i think 56.25%mm(Vertical 100%),100%mm is better for game weapon has recoil,0%mm would be better for game weapon dont having recoil
that is why in call of duty,overwatch,people always use 0%mm for ads and zoom sens,and r6,bf1,csgo using 56.25%,75%,100%mm
english is not my first language,forgive me
