Slight Problem with Eustace Bagge

[Starter_Pack]

So, I just have a slight problem with Eustace Bagge's profile. Particularly, his Stamina. This is what it is currently listed as:

Very high (In Aqua Farmer, with enough training, he could outperform Jojo, a highly skilled and athletic dolphin at a water park. Dolphins generally have higher stamina than humans, and Jojo would have even more due to his training)

You see, the problem with this justification is that Eustace was under severe hypnotic suggestion in order to outpace Jojo. Initially, the dolphin was running circles around Eustace, and it was only through the hypnotism Courage applied to him that he was able to perform as well as he did.

So, very simply, I'd like this justification removed, and I want a better one found in its place.
