What the comparison includes

Both sides use the shared expected primary-target, pre-mitigation direct-DPS engine. The after side adds fixed global-stat changes and the declared count/stat-scaled changes shown on this page. It includes staged damage rounding, crit expectation, projectile count, shooting duration, and steady-state mean cooldown.

It excludes enemy armor, target density, positioning, misses, overkill, burning, explosions, spawned attacks, temporary effects without a fixed duration state, conditional procs, target debuffs, and weapon-scripted damage changes. A displayed zero therefore means zero within this stated direct metric, not zero value in every combat situation.
