# Damage rate vs distance

Correct at 2.2_Jan_11_2008

Compares direct fire weapons (excludes grenade launcher, for example).
MDRx,y is the mean damage rate for an accuracy of x at a distance of y map squares
calc uses the spread modified by firedef.crouch (ie assumes the actor is crouching).
standard deviation in distance units, sigma =(pi/180)×(range)×0.5×{spread+(1-accuracy/max_skill)}×crouch
see G_ShootSingle() from g_combat.c
modelling target as 24×56 rectangle (see modelling article), this will be a slight overestimate.
hit probability, p=erf(recx×sqrt(2)/(4×sigmax))×erf(recy×sqrt(2)/(4×sigmay))
where erf() is the error function (integral of a gaussian).
