That actually clears things up. I already knew the term "section hiker", but googling the term "segment hiker" also led me to the term "flip-flopper" (a segment hiker who does the sections out of order). It seems all this stuff is already well defined. I like having classifications and labels to neatly organize everything in my brain, but in the end, I agree that it's the experience that matters.
