As the OP I think it's fair that people point out it's great but we're a long way from being confident we can repeat it year in year out
What is clear that the margins between incident and accident are small and the extent is only really visible with modern reporting that covers almost every flight incident.
But we can chip away steadily to improve the margins and focus on the items (such as runway excursions) that make up many of the incidents - this will, in turn lower the long term accident rates
