It is worth checking from time to time the huge assumption that all of the antique kata were created by great masters of their day and that each form contains a great reservoir of combative experience. A wide range of forms have made their way to Okinawa from China from many different sources quite a few of which are unknown. Perhaps not all kata were born equal and produced by experienced experts, perhaps money making opportunities were seen from local amateurs of the day who had no practical experience but were great salesmen!(not unlike many so called masters today). This is also reflected today in the endless applications, flow drills and bunkai exercises that are clearly made up by the instructors and sold on.
Some forms are undoubtedly combative masterpieces, but are all kata?
