Glossary
Every metric, term, and concept used across Lucent's weapon analytics — defined.
TTK Metrics
The average, or mean, of the TTK distribution.
The TTK represented by the most frequent outcome of the TTK distribution.
The TTK represented by the 10th percentile of the TTK distribution. Reflects a realistic best-case scenario — a more favourable TTK.
The TTK represented by the 90th percentile of the TTK distribution. Reflects a realistic worst-case scenario — a less favourable TTK.
Various forms of TTK integrated over a distance probability distribution using log-normal models calibrated by weapon class.
The probability-weighted average deviation of a weapon's TTK from its most likely (Modal) outcome, integrated across engagement distances using the same log-normal distance-weighting as Weighted TTK. Lower values indicate a more consistent, predictable TTK.
Damage Metrics
Total expected damage dealt across a full magazine, derived from body-hit probability-weighted damage per shot at a given engagement distance.
Expected damage dealt per second of sustained fire, derived from body-hit probability-weighted damage per shot and fire rate.
DPM integrated across engagement distances using the same log-normal distance-weighting as Weighted TTK.
Accuracy
The default accuracy mode, assuming every shot fired lands. A baseline for comparison, not a realistic hit rate.
A Pro feature allowing per-weapon accuracy values based on your own tested performance, applied to E[TTK] and damage-based tools.
Simulation & Methodology
The dataset of Monte Carlo simulated TTKs for each weapon's damage profiles, where hit locations are sampled with probability weightings. 15,000 simulations are run per profile. All TTK metrics are derived from these datasets.
A mathematical technique that models the probability of different outcomes by running thousands of randomised samples.
The number of shots required to eliminate an opponent at 300 HP — Warzone full health with full armour. Varies with hit location.
A range bracket within which a weapon's damage values are constant.
The point at which one damage profile ends and a new one begins. Generally accompanied by a reduction in damage values, resulting in increasing shots-to-kill at longer ranges.
The probability of a shot landing on each body region of a hitbox in a simulated engagement, based on competitive gameplay.
The probability distribution used to model expected engagement distances by weapon class.
Weapon Mechanics
The elapsed time between firing the first shot and target elimination.
The rate at which a weapon fires, expressed in rounds per minute (RPM).
A first-shot delay present on some weapons.
The initial projectile speed in metres per second (ms⁻¹). Determines bullet travel time and the hitscan range of each weapon.
A mechanic where bullets hit exactly where you are aiming, with no need to lead your shots. In Warzone, all weapons behave as hitscan within their respective hitscan range.
The distance within which a weapon behaves as hitscan, calculated as the distance travelled in the first 50ms of bullet travel. Beyond this distance, bullets are modelled as projectiles.
Time in milliseconds to transition from hipfire to aimed-in.
