Overkill and rounding

You might say: overkill, wasted damage, damage waste, final-hit waste

Overkill is the final hit’s post-mitigation damage minus the target’s remaining health. The rounding policy—floor, ceil, nearest, hidden fractions or rounding only for display—decides whether that waste and the next breakpoint are real.

What it does

Separates weapons with the same HTK, exposes wasted final-hit damage and makes the damage pipeline testable instead of assuming that displayed integers are the simulation’s integers.

Ask

How much final-hit damage is wasted, and exactly where does this implementation round?

Typical

record pre-round damage, post-round damage, remaining health and final-hit overkill; specify whether rounding happens once or on every event

Trouble

Per-hit flooring silently accumulates loss, hidden fractional damage moves breakpoints, or a large final hit wastes ammo and cooldown time despite matching another weapon’s HTK.

Higher values indicate poorer ammo efficiency, especially relevant for breakpoint-sensitive builds.

Unverified: No universal rounding order applies across games; verify whether the implementation stores fractional damage, rounds each event or rounds only the displayed number.
