I'm personally a fan of what Jack Chen is doing. Recreating an art from manuals is hard work. I think he's doing a pretty decent job. However, the problem is that it's just him and his group. The advantage HEMA has is that the amount of fighters is in the thousands, constantly refining and fighting each other. That's a huge reality check. If the HCMA scene takes off, then I think you'll find it have similar results to HEMA. As it is, they are behind the curve a bit. Scott Rodell once stated that the CMA guys are about a decade behind HEMA folks (ARMA specifically at the time). Given the difference in numbers, I don't expect that gap to close any time soon.
