I'd very much like to see a reference/citation for this, as it flies
in the face of both deeply held religious beliefs and also most of the
available data (e.g.  Reifer studies, AFATDS preliminary data, etc).

p.s.  I've seen some people come up with higher start-up costs for
Ada.  (In part due to retraining, learning the language, etc, and in
part due to front-loading the life cycle by spending more time doing
design.)  It's possible that someone took the delta from start-up
costs, and applied it into his favorite old-fashioned cost model to
obtain linear cost increases.
