So... a few weeks (or so) into knowing this guy from church, my friend and his wife are awakened by a lone guy standing over them in their bedroom, with a flashlight and gun pointing at them. (at this time, my friend was friendly towards guns, but not educated, skilled or prepared with one). They were ordered out of bed, and to start tying each other up (in some way). When the badguy hesitated, my friend lunged at him and my tackled him, and began a wrestling match. The wife grabbed a bat, and beat the BG pretty badly. Quick thinking for a couple of folks with no personal defense training. They lived, those are the details that apply to my answer to the OP.
I have also personally conducted the 21-foot rule with a well-trained instructor and well-practiced shooter, drawing from open carry and from concealed carry. He'd get cut EVERY time when I'm covering the 21'.
I put those pieces of info together, and I don't want to waste time to rack a slide....
