As far as I understand from what I've read, Iran even separated the attack times of missiles and UAVs to make them easier to monitor and shoot down without overloading air defense systems. For example, Russia deliberately syncs these attack with large numbers of aerial weapons to overload Ukraine's air defenses beyond their capacity—Iran could not have been unaware of this tactic, but it chose not to.

Right after the attack Iran's permanent representative to the UN stated that "The matter can be deemed concluded. However, should the Israeli regime make another mistake, Iran’s response will be considerably more severe". It looks convincing that Iranian pyrotechnic show is more of a reputational response, given that some of the targets were shown in propaganda videos days before the attack (if not directly leaked to Western counterparts so that Israelis had time to prepare and/or evacuate personnel).

they separeted the launch times so that slow and fast things would arrive at once. That meant the world had hours to shoot down slow drones.
