There is so much that has to go right for that to come even close to working.
I don't do many techniques that require me to process that much information in that short a time frame.
Again at speed people cant move their hand in the way an inch or their head out of the way an inch to avoid a honking great big obvious punch.
Which means you have to set that shot up about two moves ahead. Which is not really my idea of self defence. Because I want a move I can just do.
See punch.
Not get knocked out.
Then progress with the fight.
