It is well explained in this post , Admin please look into this , as even i feel better with this method of conversion
before i was overshooting alot , i came from csgo (Lem) so i could tell something was off in the sensitivity , it was higher , correct value of conversion is
csgosens / 3.3735
idk about the 2.5x scope conversion tho
Admin please test and check and make changes accordingly
Thanks for reading
