That logic only works if either A: The initial point is so ludicrous it needs proving. If I say that I can punch a hole through a tank, you need proof of this. That a martial art teaches you to fight needs less proof. B: You would expect to see proof of it. If the tournament was created by bagua guys interested in marketing bagua, then the lack of them would suggest something. If it is a tournament for all of china, with over 100 different styles and 15 people attending...the lack of one style means a lot less. Again, I did not see hung gar or fu jow pai on either list, but those are the only two CMA styles that I personally know have good practitioners. By using similarly flawed logic, I can make the assumption: 1. Hung gar is a good CMA, that produces good fighters 2. This tournament was open for all china, but there was no hung gar there. 3. Therefore, this tournament must have not had good fighters.
