Master Black Belt
I think your bolded comments say more than most in this thread. It is very rare to see people speak of their black belts without naming the art they have them in. I have to wonder what they are hiding. I would be more trusting of someone who stated they studied several MA, but that even though they never achieved BB in any, learned a lot they thought if combined, would make a good MA, and started a school to teach those things.
From the videos it looks like one might get good training in cardio. One may even get MA training. I would need to see more to comment for sure one way or the other on that.

I agree that it seems odd that they don't list who they earned their ranks from or what organization. As a martial artist looking for a school that would be something I would look for because it would give me an idea on what they teach or how they teach it.
However if they are no longer associated with the organization, or if they aren't really teaching say ITF style (I'm just picking out a style of TKD here) TKD, anymore than what does it matter? In fact it stirs up more controversy, because someone on forums like this will call them out and say they are fakes and such, or they haven't been part of this organization for so long etc. etc. Instead it appears to be downplayed because it's not important to them (business wise) or their potential students who they trained with. They are teaching a blended art, parts of other arts to make a whole art, they aren't claiming to teach all of the arts contained within Konsei Martial Arts, just parts of them. Kind of like teaching MMAs with the emphasis on being healthy, fit, changing the character (lifestyle) and self defense instead of sport MMA.
For the general Mom and Dad looking to enroll their kid, or doing a family activity together, or someone looking to get into shape or make some changes in their lifestyle; they won't care about your styles lineage, your history, your rank etc. etc. They will care about the price of lessons, the school (location, cleanliness, equipment, lessons etc.), the instructors skills and appearance, and how they are treated. They won't know going into the school how effective anything is (just like the o.p. here) so they will care about the other things first. However we as martial artists tend to look at everything backwards compared to someone who is just entering the martial arts; we'll over look a lot in the shape of the school, travel farther, pay more, etc. etc. to get the training we want from who we want (and the instructors history is part of what wen want to know).
So their not listing their histories, or giving long winded explanations of what they take from where etc. etc. can be a simple business decision on their part not to muddy the waters for the new potential students rather than them being fakes or hiding something.
