First off, Hulk got ko'ed by 133 hercs.
Second off, rao is playing smug when he's literally saying that an entire run who's sole purpose was to wank Hulk has Pak lying when he specifically went out of his way to make up a measurement system to wank Hulk. How does this work?
Third, he later did the same shit when he amped Wendigo and Bi Beast a thousand times and had normal Hulk defeat and kill them in a conflicting way sure, but the amp was established. Both characters Hulk really doesn't have wins over at normal power.
You could see the frustration in Pak's writing when he had shit like Cho saying "You mean he actually has to destroy a world for us to accept it?" Paraphrasing of course but the message is clear. Pak was going out of his way to try and one up everything Hulk did. He wasn't lying when he wrote the stupid shit he did. He was lying when he had to give Hulk a challenge and make people do good against him.
Not to mention Herc hitting him was in an event with much less freedom and context. Then Pak went ballistic. Also pis exists as well, and you're speaking about the definition of a character with fluctuating strength.
