Let me just say that after reading your very spirited post, it still stands that "30 something" tenth dans are widely considered anomalous.
By whom?
Nearly every Japanese art going back in history has provided "menkyo kaiden" or equivalent "mega dans" to individuals under the age of 40. And that includes even the most well-known Koryu schools as well.

It has already been explained that Soke Hatsumi's ideas of rank do not correlate to kyu-dan ranks given in other martial arts styles. I believe you have posted in agreement with this position yourself.
I have posted that it is inappropriate for people to compare ranks within the Bujinkan to other individuals within the Bujinkan and to compare ranks in the Bujinkan to ranks in other arts. Similarly, it would be inappropriate to compare a 5th dan in Aikido with a 5th dan in Gosoku Ryu Karate. Each has its own requirements, and neither dan holder could hope to pass the other's "requirement" easily.

Are you equating "30 something" 15th dans in the Bujinkan with the likes of Yagyu Jubei Mitsuyoshi, Minoru Mochizuki, and Koichi Tohei?
My question back is: "Why couldn't they be?"
There are a lot of people out there who are somehow convinced that individuals these days can never achieve the greatness that others have achieved in the past. I think that is sad.
Hatsumi-sensei says that he will train us to be better than he is. And, silly me, I believe it can be done *IF* we listen to him.
There is no doubt in my mind that some of the individuals who hold the highest rank in the Bujinkan were at a level in their understanding of their Budo that Mochizuki or Tohei had when they were awarded the highest rank in their own arts.
Alas, this has nothing to do with their "rank" per se, but with their training. That's the point.
As to Brian's point, the positives of the Bujinkan ranking structure are that:
1) Each teacher is free to judge the basis of what should be rewarded and what should not be rewarded. Seeing how each student is merely replacing their own habits with those of their teachers, this is a good thing.
Each teacher has certain things that s/he does well and certain things that s/he doesn't do well. It is best for people to teach what they do/know well, and for them to allow their students to seek out others to fill in other holes.
2) Students learn at different speeds, so someone may take longer to learn "Ura Gyaku" than someone else, but that someone may pick up fancy footwork faster. A grading system that would require someone to absolutely "learn Ura Gyaku" before advancing could severely hinder the growth of an individual if that grade was necessary before learning "new stuff."
The Bujinkan way of grading is completely in line with what we understand about how the human brain processes information and makes connections between seemingly unconnected things. For all we know, a sword cut learned after getting the fancy footwork down *COULD* lead the student to understand what he was doing wrong in his "Ura Gyaku"!!!
3) Rank is always personal and allows one to know how one personally stands compared to where one was before.
4) It adheres to the same spirit as old arts in the history of Japan.
5) We have five additional levels above those aikido guys, so we can wallpaper larger rooms!
