While I agree, isn’t breaking pretty much a staple in TKD and the various Korean arts’ practice and rank tests? I don’t think I’ve ever heard of a TKD or TSD test without a board breaking requirement. I don’t know enough about Hapkido to make a generalization. I’m not a fan of it being a testing requirement personally, but if their standards are X amount of boards using A,B, and C techniques for Z rank, then those standards should be evident whenever you see someone wearing Z belt. Maybe not every single person at every possible moment, but if you see a trend of people consistently not being able to do what they’ve allegedly been required to do and prove they’re capable of it along the way, then “Houston, we have a problem.” I mean, to an outsider such as myself, breaking seems to be one of their gold standards. They sell it as proving the power their strikes have without hitting each other with full power. I don’t know of any art that puts nearly as much emphasis on breaking as TKD and TSD.But what if those are not requirements at a given school? I considered using red as one of my belt colors at one time, and it would have meant something entirely different (which might or might not have included the ability to kick at a resisting target). And what if black belt doesn't mean "any good", but "can do the basic moves"?
I have my personal bias about how I like ranks to be used, but I have to admit that others don't have to share that to be "right". Since I wouldn't be bothered by a school that uses no ranks, nor by a school that decided to use orange, red, and grey belts (colors I've never used in training) to mean whatever they want, I accept that they're also not wrong to use black, brown, purple, green, blue, or yellow to mean whatever they want.
