Well I'm glad that things at least sound like they have substance, as that's my real goal. I will say that these ratings are some ideas and I'm not saying that he's not CAPABLE of monster belches ever. I definitely believe that Wriothesley is. And this was for burps only, I do think he definitely can eat a ton as well.
Personally, I think characters can be complex, though not always absolute, with a lot open to interpretation especially in things like this. There is his character design but also what we know of him with his personality and setting. In this case, some of his personality and behavior conflicts with his "carnivorous" design. I do think he's capable but it also depends on who he is with and situation.
There is one more wrinkle to think about here too. Wrio is a plotter. Half the time, he's trying to disarm people to make them relax or intimidate them. He'll do what he needs to get information out of people.
So he can have manners when he needs to, especially when that gets him farther in society, especially when it disarms people in the Fortress who revere him and think he's unapproachable. Or those in the outside that think he's just a ruffian but he's "respectable."
But when he needs to, he can be one of the guys, crude, lewd, whatever else especially if it's a smaller gathering. He can hang out with other fighters during Pankration Ring matches or checking on him them. If that includes burping or eating then he'll do it.
If he knows that someone HATES or LOVES lack of manners and overeating but needs information from them? Well then they come to his office and he proceeds to eat everything and burp and slurp and pat his gut just to get a reaction.
But this is why sometimes thinking of a particular scenario or situation comes with a clearer answer because it's easier to predict behavior or if there's a reason they might act a bit out of character.
