I don’t think he was trying to cheat. He seemed to have combined the rules of ionization and how it affects small, medium, and large ships with the stress rules.
I like him a lot but he gets hung up on things. Like the conversion kits. His empire kit came with 10 medium base ship dials, so he was convinced that the kit should have come with 10 medium bases. I tried to tell him that there is no way you could squeeze 10 medium ships into a 200 point list, so 10 medium ship bases wasn’t needed. He disagreed. He opened cases with FFG and ASMODEE to no avail. But I like him.
