A FANDOM user I think you are too hung up on titles. Understanding and actually doing it are two completely different things. If understanding strength is all it took then Issei would never even considered challenging any of his opponents. He knows full of his opponents strength and even if he knows there stronger, he won't stop until he finds a way to win and to protect what's important. So far it works for him.
