Check Joe Rogan video link in previous post. He is right about these Masters getting beat down when tested.The Gracies beat many of them from different styles, then when UFC came those that tried in there failed badly.
Take a look at this Japanese Ki Master in action :
Even with no touch he drops people.
Now see what happened when he faced a MMA fighter, the Ki Master claimed he could beat anyone :
None of his Ki power stuff worked!
Here is William Cheung master of DimMak & Wing Chun :
Never fight twice over a skipping rope!
Now here is William Cheung after claiming he could beat anyone and was the best fighter in Wing Chun :
Beaten easily and at one point got his arm pinned, if the guy wanted he could have gouged William Cheung in the eyes then. William Cheung's people had to pull the opponent off him as he was defenceless and getting repeatedly hit in the face.
Mikhail Ryabko showing Russian Systema strikes :
If this really works, enter UFC or Boxing win World Titles and KO everyone you meet!
No doubt the same would happen for someone using George Dillman's Pressure Points and no touch KO's, yet these people have no shortage of people wanting to learn from them.
