Yep, its a shame...and wildly inaccurate as well.
I admire what Bullshido tries to do.....I have little respect for the level of discourse that is typical over there.....their methodology tends to be all over the place in terms of quality as well--some of it is top notch---some of it ain't even close.
It proves nothing...beyond what limits there are in the test itself and the skills of the specific people invloved.....also speaks to testing bias of course.
All martial arts are essentially self-justifying and self referencing-----it either works for the person using it or it does not...EVERYTHING else is theory.
If "my" wing chuan, karate, hung gar, tai-chi, TKD, sambo, boxing etc worked when I needed it to then it worked period.
What someone else was able or unable to do with it is irrelvant to the question.
If it didn't work then there is a considerable amount of questions as to why it might not have---starting with the person themseleves--then whom taught them etc.
It might very well be a case of simple running into the guy/girl that has your number--maybe they were just a better fighter....happens to everybody..in every art...even Chuck Liddel gets beat every now and then.
And most of us are no where near the fighter Chuck is.
