What an utter load of bollocks that paper is - there is no real data in it at all, just simulations, estimations and comparisons with no basis in reality.
Exactly how the minor and major servicings could be reduced in duration is not even hinted at but that is the main thrust of the paper - reduce duration of servicing to increase availability.

The paper was written by a non-military, non engineer whose job appears to be playing with statistics and we all know the old adage about them.

Does integrity and reputation count for nothing in commerce any more??
