Statistics are an interesting thing.....it takes more than a single snapshot to be usable as reliable indicators of prolonged time periods.
Did you consider the issues raised by the POGO Report with any real thought or are you just throwing out a factoid without context and thinking it means something?
I have seen the serviceability game played at every single Flight Operation I have flown.
The ultimate was walking out upon the ramp to my assigned aircraft....a CH-47C that had been put up as "Flyable".....which it was.....with just a single engine hung on one side and none on the other.
Take a whack at the POGO Report and take its comments apart....they might have it all wrong I suppose.
