My general rule in these cases: "1 is the worst number of times to do something" -- 84M for documentation for 2 airplanes seems like a lot. It looks a lot better if you have 84 airplanes or 8,400 airplanes. Alternatively, cost isn't so bad if those 84M manuals and the 2 airplanes are useful for 50 years.
