I was going to add to my post, but it got late...
Pretty much all of those near emergencies "self-resolve", with the people getting out on their own, or their companions', power. I am told Doug at the store calls them "Saturday Night Specials". I've seen an estimate that there could be more than a dozen of these a day(or night) during the busy season.
Bob R has told me about one time, a guy met him at Trail Camp around sunset, on a day Bob was wearing his ranger uniform. The guy asked if the rangers swept the trail, from bottom to top, at the end of each day. He was worried because he could see a few headlamps descending the 97 switchbacks.
People just don't realize how much they are truly on their own when the step onto a trail.
