I have no clout on this forum but here is my two cents as a Hung gar stylist and Tai chi practitioner...
I love to meet people who have immense power whether internal or external it is inspiring. They all have their own formula and have spent many hours developing it. Honestly though it takes little energy internal or external to drop someone. Lightly slap your palm against the back of your neck or (a little harder) against your friends
Did you get tunnel vision or see lights?
Heavy bag killers and one inch magicians are all awesome but still need those closing skills.
Now I'll shut up and go back to my horse stance.
