I don't really understand your comment. My previous statement was simply about the likelihood of needing to engage at those distances. You said you have read through plenty of examples. What's your sources? Can you produce them?

I've seen footage and read through compiled stats of thousands of real-world civilian defense scenarios over the past few years and have only come across a handful of armed civilian incidents that occurred at the ranges you mentioned. And most of time when they did engagement wasn't absolutely necessary. Because of that, I have never spent much time working at those distances since there is relatively little need for it and much more important things to work on.
