Weapon spread



Weapons Spread determines the accuracy of a ranged weapon in degrees. Formulas here taken from the GECK wiki.

Spread Computation
$$\begin{align}\text{total spread} = \text{aim spread} + \text{weapon spread}\end{align}$$

The total spread is equal to a spread due to the character aiming, and a spread due to the weapon itself.

Aim Spread
$$\begin{align} \text{aim spread} = \text{perk effects} \times ( \text{state effects} \times \text{skill effect} \times 1.5 + \text{limb condition effect} ) \end{align}$$

State Effects
State effects combine multiplicatively.
 * Crouching reduces spread by 60%
 * Using iron sights reduces spread by 35%
 * Walking or running increase spread by 100%

Skill Effect
The appropriate skill (Guns, Energy Weapons or Explosives) reduces spread by 0.5% (from 50% up to 100%) per skill point.

Limb Condition Effect
Damage to limbs increases (pre-perk) spread. A one-handed weapon will have spread increased by 0.5% if the right arm is crippled. A two-handed weapon will have spread increased by 0.25% with one arm crippled and 0.50% with both arms crippled.

Weapon Spread
Weapon spread is equal to the Min Spread stat of the weapon in degrees. Weapon Condition has no effect on spread.
