Maybe it's distance dependant as well.
Even when I changed the accurancy of my weapon (a pistol) to 0, it still took three hits for the enemy to die. (this was when I shot him at close range)
At a distanced range it took four shots for him to die. (I think all bullets hit him, but I cannot be 100% sure that every bullet hit the target, I could have missed a shot)
Verywell! I could include that 'extra' bullet in my calculation. But It would be fun to know the excakt reason for this and how it is handled.
But I thank you guys. Yoyr replies halped me. Thanks!
