Recent field studies have concluded that cartridge-based projectors perform best when given adequate time to cycle.
By definition: Cycling implies the ability for the gas chamber, within a cartridge-fired projector, to replenish itself with fresh oxygen. When achieved the projector yields a more consistent burn rate in each charge fired. Failure to do so results in less oxygen yielding lower combustion levels (e.g., reduced muzzle velocities) for subsequent RDDs fired at less than 30-second intervals.
