You're forgetting the common predatory criminal has overwhelmingly ceased criminal activity upon being shot based on the link I provided.
Criminals choose their victims based on perceived weakness and little to no combat required to achieve their goal.
Unless you are targeted for a gang execution you're more likely to fire off a few rounds and have the assailants flee or give up.
It's extremely rare you're gonna have an extended fire fight in common encounters.
Definitely train for it. Cry in the dojo laugh on the battle field.

We don't disagree that much.
The NRA study posted above was for successful cases of self defense. The homeowner was successful in part because the perp was unmotivated or amateurish.
Get a perp who wants to kill, or wants to die, or is crazy with racial or religious hatred and he would have walked all over most of these homeowners.
Again, getting a shot or 2 in a perp and getting shot yourself before he passes out is not a good outcome.
What we disagree on is the initial shooting zone. You say train for head shots. I say go for higher percentage hit zones
first. I never stated 2 and stop. 2 minimum.
Again I don't get to choose time, place because I'm not out there looking to rob people.
I'm less likely to make precise shots:
in the dark, at 3am, just being woke up.
having my business stormed with armed men as I'm helping a customer
eating dinner with the family as someone is kicking down my door
et cetera, et cetera, et cetera.
Adrenal dump and the chaotic environment is going to be a sensory overload for most people to be calm enough to focus on the front sight to put one or a few to the dome. Again, add in movement, fear, confusion, dynamic speed of how the situation changes in mere seconds is something a lot of people disregard in their training.
My first 2 shots are going to be chest box. My next shots will be dependent on a variety of situations I'll never be able to train for.
So I've trained:
Standard response - 2 chest box
High response - 2 chest box, 2 head
Low response - 2 chest box, 2 pelvis
Timed, in the dark, one handed, slow, fast... what do you do when you run out of ammo and the perp is nose to nose with you and you don't have a chance to reload?... I train that too.
You're out in public and shooting starts... you're with your family... what do you do... I've had a training course in that too. communication, prior planning as a family unit, how to shield a loved one and shoot, cover/concealment, cover fire, emergency tourniquet. And that's assuming you're not the one who was shot first during the gunman's initial rage.
Admittedly, my focus has been competition most of this year. But I've also have some funds set aside for a few 8 hour defensive courses for 2017 to reinforce the 5 other 8 hour training courses I took in 2014-2015.
