Yeah since they would've been the first Irregulars, or some of the earliest, Headon may have just given them normal tests, and maybe he only started making them harder once he realized they were too easy for guys like Enryu, Urek, and Pentaminum.

Since Headon has authority over his floor, I'm guessing he can probably do anything he wants. It's just that since he seems to be near-omniscient and all, he would know what's best, so he generally sticks to the rules. A little like the concept of God.
