if fedors limit on punishment is exceeded, he will be defeated. the way punishment limit is exceeded is through forceful blows.
That's where countering comes in.
Avoid punishment and counter when the opponent attacks. Be unpredictable.
The only one who made Fedor wobble like a duck was Fujita back in the day, where Fedor had to clinch, but due to his great recovery, he was back in action very quick after.
And don't forget the Randleplex, that didn't even seem to phaze The Last Emperor.
