I don't personally know the author, but I am impressed with this article he penned.
Too many instructors don't know nearly as much about a subject as they pretend to, and it is a huge pet peeve of mine when people fall back on "it depends" too often. Sometimes it does depend, but then you need to lay those circumstances out. Many other times, "It depends" means, "I don't know". In LE training, as well as some of the mil training I have been fortunate enough to attend, this "shooter's preference" is widespread and often misapplied. He goes into greater detail, so read the article.:-)
I put this here because I think of this as teachers mindset, but if there is a better place for it mods, please adjust accordingly.
