Neal - I'm sorry but you show ignorance of statistical decision making. There is no necessity to go the extremes of Tactical Timmy. As said quite a few times, one decides not to act at a measure of central tendency but for a reasonable cut off in the tail of incident intensity. From good ol' null hypothesis testing, you can decided your statistical power and Type I error cut offs (.01, ,05, etc.)
No, I get that, but I don't think you got my statistical 'big picture' point I was making with my illustration of a roll cage for your passenger car. I wasn't talking about statistical decision making on carry and reload options within the context of a gun fight, or 'intense incident'. That's up to each person to analyze for themselves, and then choose what works for them. I was talking about statistical analyzing and decision making, with regards to threats, in the context of your ENTIRE LIFE. The life you actually lead within your quiet, boring 'day to day' world, not wild hypotheticals you dream up online.
It's like if we step outside and look at the world around us, metaphorically, as the endless possibilities of potential threats to our health and happiness during the course of our lives, then hyper focusing on "gun fight" scenarios is like viewing that open world of possibilities through a straw. "Homicide", by any type of weapon, isn't even in the top ten leading causes of death for white males in the US according to the CDC. The top four are; Heart disease, Cancer, Unintentional injuries (like car accidents, etc), and Lung disease.
Hell, I've only been in one legitimate life threatening incident in my life involving a weapon, a carjacking at gunpoint, but I've almost been in a head on collision with some moron looking at a cell phone bi-weekly going to and from work everyday. Almost every older male in my family has died of cancer and heart attacks. That is reality. The people actually worrying about vehicle reloads for a hypothetical extended gunfight, or whether to carry two backup mags or just one, probably aren't as worried about what their eating everyday, or if they had their yearly checkup, or if their car's brake pads are still tip top.
I was just trying to illustrate, in a light hearted way, that this sort of hyper focus on very far fetched gunfight scenarios is silly for 99.9% of us (excluding cops, deployed military personnel, and mercenaries), and it can quickly spiral into the absurd, all to the profit of your local LGS (so at least it supports capitalism
) Carry whatever you want to carry if it makes you feel good, and doesn't get you arrested. Just don't get lost in the deep end of hypotheticals!
