From a passenger view, the delays. Arguably the timetable doesn't work if it needs 15 minutes to recover half the boards, especially if it's spent the last 40 minutes, running 15 minutes late.
Obviously no arguments about you can't have more layovers - I wouldn't expect it and I haven't seen the timetable so there might not be delays - hopefully.
