If you are going to argue Stats....let's get back to the one that got a lot of this discussion going.....the difference between Norway's Safety Record and the UK Sector's safety record.
The salient "Numbers" to me are simply the number of Accidents/Ditchings, and Injuries or Fatalities that occur and the determination of the causes of the them.
In a perfect World....the number would be a simple "0" but we do not live in a perfect World.
We have to determine the causes for the events, analyze them and determine how to prevent them from happening again by doing an honest evaluation of the system, procedures, and standards extant.
Rather than arguing over the extent of the problem you define by the creation of your "numbers"....why not just agree something needs to be done to reduce those "numbers" to as close to "Zero" as possible and offer some ideas that would work to do that.
Like it or not.....the North Sea UK Sector has a problem. You can deny it, spin it, but in the end....you are putting aircraft into the water and killing people.
