It is a shot fired by feel. My upper body stays flat against him, so I have some reference point as to where the rest of his body is. Notice that my gun arm stayed tucked tight against my Lat. By keeping my arm tight and moving my hips out of the way(in this instance to the left) I placed my gun where my pelvis was.
The average person goes out in 6-8 seconds (less depending on cardiovascular fitness). I've been put out, and I've put suspects out. There is no "good" open hand counter for this attack. That is why it is the go-to submission in MMA.
I say this with all of the humbleness in the world......if someone can come up with something better (open hand), please let me know. Show me.
BTW....I posed this scenario to Royce. This video illustrates what he gave to me as the solution. If that is what he says is the best, I have to be inclined to lean that way.
