Again I don't see how Challenging / Fighting schools will provide quality control.
Here in the USA, Challenging Sifu's or Rivals schools is not popular. If I was to go challenge the fake kung fu guy on the West side of Cleveland, he would probably call the police because I attacked him. Then he would sue me for everything I have.
Yes, old school Kwoons used to challenge each other and this was good back in the day. How will it help keep the fakes and charlatans under control? Here in the USA 99% of all potential Kung Fu students have no clue of CMA protocol and really do not give a crap about that stuff.
In essence.... Even if I was to go challenge the fake guy down the street.... No One gives a CRAP! They will still flock to him in droves because of whatever flashy stuff he gives them or fancy weapon form he teaches them.
Bai Si has it's place and I think it is a good thing, however, for quality control or keeping fakes out ...... Nah.... won't work here.
