Re: The crux of two ranks having any equality
You could just do the best test you can, and let them do the best test they can, and if there is actually a difference in quality, it will show.
Are you sure you understand what the person/s testing you is/are looking for?
Really, we are all here to learn from each other. You have an opportunity to help teach those you think are inferior than you. Hell, you have a responsibility to do that, in a way. And, you might learn a whole lot from the experience.
Of course, a few aikido folks have told me more than once that my motto might as well be "Better than you, and that's not hard...."
