So it is possible to have reinforcements every single round? Yeah, that is a terrible rule.
I have used a d4+2 to determine how many rounds of combat will draw attention, but only for a single reinforcement. The floor of three rounds is because that is 18 seconds in DnD. Enough time for other enemies to wonder if someone is just having a spat and not worth checking out or for the enemies to realize they are going to die and think of calling reinforcements being worth it over being ridiculed or punished by higher ups.

Good call. Makes sense in fantasy combat-context.
