Average means the 50th percentile only in symmetrical distributions (a stat quibble) but the point is well taken. I have always said that you should plan for a reasonable cut in the extreme tail of the incident intensity distribution.
For example, the average gun fight is close. But there are rampages in place like where I work. Our hallway is 284 long. That's not close. It is not inconceivable if you carried, that's the shot. Recall the AF military police office who engaged a rampager at similar distance.
