"Single Gun, Multiple Round, Time-on-Target Capability for Advanced Towed Artillery Cannon" by Timothy M. Kogler, Army Research Laboratory, Aberdeen Proving Ground, March 1995 (ref. ARL-MR-225) :

Quote:
Page 6 : After the impact of the initial round of a fire mission, target posture changes rapidly. Once a target is hardened or better protected, the effectiveness of subsequent rounds decreases dramatically. Soft targets typically need 3 to 4 seconds to become hard targets. The difference between this time and the time impact tolerance used in the study (2 seconds) would account for the effects of any unknown, nonstandard conditions that could affect TOF.

Indeed.

For the defunct Crusader, ORD requirement for MRSI (O-3) was 4-8 rounds within 4 seconds at ranges comprised between 5 and 30 km.

For the defunct ERGM, desired MRSI capability was 8 rounds within 3 seconds at a range of 40 NM.

For the defunct South African G6-52L (non-JBMOU compliant, 25-liter chamber variant), advertised MRSI capability was 5 rounds within 10 seconds at a range of 25 km.
