Let's get serious here.
No rank past 3rd dan is actually tested for.
It all becomes political after that level.
Rank is highly overrated and very misunderstood by most beginners (and many non-beginners as well).
Personally, I'd be much more concerned about skill level and the ability to impart that skill to others.
You may have something there. I remember some time back reading or perhaps it may have been only a dream, though I recall that O'sensei was the equavilent of ni-dan when he began teaching. One never realy knows where your teacher is comming from and where he may take you untill you are willing to go allong with him / her for a while.
