Small Guns (Fallout 3)

Small Guns is a skill in Fallout 3. This skill determines combat effectiveness with any small gun.

Initial level

 * $$\text{Initial level}=2+(\text{Agility}\times2)+\left\lceil\frac{\text{Luck}}{2}\right\rceil$$

Example: A starting Agility of 5 and Luck of 5.
 * $$2+(5\times2)+\left\lceil\frac{5}{2}\right\rceil=15$$

Description
In general, the skill raises the Lone Wanderer's accuracy and/or damage with any weapon that is affected by the skill. The higher it is, the lower the projectile spread, and the more stable scoped weapons, such as the Sniper Rifle or the Scoped .44 Magnum, will be when aiming through the scope. At 100 points, scoped-weapons have no sway at all; however, having either arm crippled will still result in a severe sway while using the scope.

On average, increasing the skill by 5 points will increase weapon damage by ~3.5%. There is also a diminishing margin of return. In general, increasing Small Guns from 5 to 10 will increase weapon damage more than increasing it from 95 to 100.
