I find it hard to believe there is much if any area ruling on the A380. Wing fairings or not, I suspect the high cruise is a direct result of the massive amount of thrust being provided by those 4 huge engines.

You could model it like component reliabilities as in system reliability. The hard thing is determining if the reliability rates of the fleet types are in series or in parallel. Then it is either R = r1 x r2 x rn for series or R = 1- ((1-r1)x (1-r2) x (1-rn)) for parallel.
