Level Gap XP Bonus, where is it?

I THINK it's +50% regardless? But I could be wrong, I have 3 L50s already so I can't know the difference otherwise

According to the text in-game, the bonus changes depending on the difference between your highest class and your current class. The game even tells you to keep this in mind when deciding on the right time to level multiple classes.
