What am I looking at?
All figures are minutes before scheduled departure. A negative number means the value appeared after the flight was due to leave — common on delayed departures, and kept rather than discarded, because it is real signal about how this airport behaves under pressure.
n is how many publications the figures rest on. Below about ten, treat them as anecdotes.
