Vaccine man can`t be  DLvl God 1, at most a DLvl Dragon 3. Even though he was created by Earth to wipeout mankind, he wasn`t able to take a punch from Saitama. Everyone on this list whos gained  Disaster Level God 1 was able to take a few of his serious hits. Vaccine man got done in by one of his normal punches.

About Seaking, that seems about right to me. Despite Genos being a little stronger than he was in the begining of the series he was nothing compared to Aura Rhino at the time. The guy literally blew Genos` energy blast away with just his breath. So from we know from the House of Evolution arc and from the Seaking arc assuming Genos did get stronger. It would make sense for Seaking at full power to be DLvl Dragon 1.
