The 70% rule is something he mentions quite frequently, ex.
He has a number of videos on the topic. Now, in general, I would say, he is correct.
But, is it really true i.e. if you have been around for a while you have surely seen ways to 'go 150%', if you needed to.
Do you think there is room for 'going 150%' in Tai Chi, or is a 70% rules fundamental to Tai Chi as a whole?
