I'm somewhat suprised to see you refer to this as a "problem", since you've indicated in the past that you've done the very same thing any number of times with KKW Dan certificates. If it's a problem, why do you do it?
Try reading the part that I quoted, and not just what I wrote to understand what I was responding to. Master Weiss' hypothesis is that Kukki Taekwondo has looser standards but that led to large growth and that ITF on the other hand had stricter standards but that may have limited growth. The "problem" regarding his hypothesis, is that General Choi gave rank based on looser standards as well, and I gave some examples. The "problem" is not grandfathering in taekwondo practitioners who are using other curriculum into kukki taekwondo, in much the same way that houses built on a different set of standards from an older era need not be torn down simply because they fail to comply with today's building codes.
Does that answer your question?
