Your SPARK papers often contain interesting numbers which give some
idea of the size of the problem tackled; and yes, they often claim
'magical' properties for using SPARK.
The number of greatest interest never appears; cost-benefit.
Your customers seem to be companies involved in projects
where the cost of failure is peanuts compared to the cost
of throwing some money at finding problems, plus being able
to identify a manageable chunk of critical code that needs
thorough checking.
Being able to identify a manageable chunk of critical code
is crucial, simply analysing everything is rarely practical.
