TTK and damage

A hit starts at the projectile damage for that caliber. Buckshot multiplies by the pellet count only when the buckshot item text is a single number of pellets, and the count assumes every pellet hits. A slug that repeats the same sentence is not treated as buckshot. Distance then scales by the weapon falloff curve. A straight line joins the stored points. When a segment is marked Cubic, the file has no tangents, so the line is only the straight stand-in and the result says so. An empty curve is not a hidden 1: the distance factor is left off and the projectile damage is used as stored. Past the last point, the last stored multiplier is kept.

Two hit-zone numbers are both applied: the universal profile and the profile for the weapon class. A missing class profile leaves the hit blank. Hollow point and armor piercing then take the untargeted infantry ammo rules (+100% and -20%). On a zone the selected vest or helmet lists, the piece's damageReduction is removed as a percent and the most specific targeted infantry rule for that plate is applied once. A family rule and a level rule are not stacked. The generic Armor and Helmet rows in the damage file, including the -60% bullet row, are not applied on top of the piece. Ghillie pieces have no covered zones and no reduction, so they are not a choice. Weapon-specific rules whose token does not match the item id, including the M1911 row, are not applied.

Shots to kill divide 100 by the hit and round up. That 100 is not in the dataset. Time is the gaps between the first and last shot at the stored rate of fire, plus flight at muzzle velocity. Reload, burst delay, and recoil are not in this sum. A missing rate of fire leaves the time blank.
