Weapons 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

${\begin{aligned}{\text{aim spread}}={\text{perk effects }}*(&{\text{state effects}}*{\text{skill effect}}*1.5\\&+{\text{limb condition effect}})\end{aligned}}$

State Effects

State effects combine multiplicatively.

• Crouching reduces spread by 40%.
• Using iron sights reduces spread by 65%.

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; this is linear with the limb condition.

• Damage to the arms increases spread by up to 1.5 degrees.

Weapon Spread

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