Everyone speaks of the gap in 6th and up Dans. I know a few that I could rely on, but I do not see the whole picture so I truly have no idea of how large or small that gap is.
The gap is huge. Try and add it up. Name all the American borns you know who have Kukkiwon 6th Dan or higher AND are promoting people using Kukkiwon certification.
What I do know, is that it is easier today to promote through KKW than it was during the mid 80's thru mid 2000s and many more american masters can do so...
Good.
