Actually they are passengers who purchased a discounted ticket which does not allow them to select a seat. Since they purchased a ticket they are obviously ahead of all non-revs.
I have heard that they are included in the Travelnet numbers but the problem is they seem to magically appear out of nowhere as you get closer to your flight - Thus the Hope -Killer.

To add to what Scoop wrote, they can also be misconnects from an earlier flight, or deadheaders of the last-minute variety.
For instance, at least one Delta Connection carrier does not book deadhead seats until 9PM central time the night before the flight, even if the trip had a deadhead in it the whole time since the bid award came out weeks prior. 0/-3 suddenly becomes 0/-7, at 10PM for a 7AM flight.
