Answer:- When you change the system.
It is now claimed that the near miss by the Virgin Blue B737 near Melbourne recently was NOT actually a near miss.
It apparently cannot be declared a near miss under the new system, because under the new system there are NO figures laid down for how close a near miss is.
Under the old system it would have apparently been called a near miss.
So, obviously the new system IS much safer, as there will not be any "official" near misses.
Reminds me of "Yes Minister/Yes Prime Minister", you can use figures and statistics to prove whatever you want.
