Well I just disagree with you about 60% - I think you're right about 40%. Physical fitness in general, and hand to hand training in particular, IS useful, and COULD save your life. But it's not the most important thing. The attitude to fight is the most important thing, which one can have and I do have without any MA/HTH knowledge. The second most important thing is having the right hardware, and the knowledge and skill to implement them (handguns in particular) quickly and effectively. Third would be general physical conditioning in case you need to run away or fight for control of said hardware. And a distant 4th would be actual attacks or counters to MMA or machete nonsense. So my view is different - the root of gunfight is GUN, not fight....
Perhaps Exhibit "A" here will illustrate my point:

Obviously, you are a very wise and learned instructor and fighter, so your mileage may, and does vary. Again, though, I'm agreeing with you mostly - I just think it's more like 60%/40% hardware over software.
While I thought that was a great movie scene, the reality of it is that "Hardware" only amounts to about 1% of the solution.
"Attitude"...or mindset is very important.
One thing is very clear though....nobody ever got better at anything by NOT training.
