How do you know how much power and strength is being used from a video??
Nobody is "fighting" in any of these chi sau videos so you have a valid point.
I can only speak for myself but stopping an MMA fighter is the last thing on my mind. Why bother yourself with such things? Your thinking suggests that ALL combat systems should prove their worth against MMA. It's a pointless discussion IMO.
One thing you are forgetting Alan is that a street fight doesn't go on for too long in most cases. The result usually depends on the power of the strikes and the amount landed. Just because you train MMA does not mean you can knock out all comers. It depends on many factors. Too many to list so why dwell on it.
Lets look at it from a hypothetical POV. An untrained guy happens to get in some bother with a guy who trains MMA. The untrained guy blind sides him, knocks him to the floor and kicks his head in. Who is the better fighter??? You couldn't even answer that question because the next time it may be different.
Until somebody punches you on the chin it makes no odds about styles!!! Some guys can just fight. No MMA required.
I wish you would stop putting everything about competition Wing Chun against competition MMA. There is no such thing.
Who would win out of Tyson and Ali??? Another stupid pointless question but rages on and on and on.
You could probably pick two guys from this forum and ask them to fight. One may win in the club/ring but lose out on the pavement. How do you know? You never will!
I'm yet to see any good VT sparring on YouTube. You have more chance of finding rocking horse sh8t!
You are right and the fact that most threads turn into garbage is boring now don't you think. Better to leave the keyboard and go face to face if anything is to be sorted out. Otherwise its just pixels on a screen.
