[SystemSafety] Save time and money and still hit 100% MC/DC

[Derek M Jones]

All,

Some evidence that there are significant savings to be had by
restructuring code to reduce the number of tests required
to achieve 100% MC/DC:
https://greg4cr.github.io/pdf/16mcdc.pdf

and yes, the smaller number of tests (over 50% fewer)
detect fewer faults in the code.

Who wouldn't want to save money and reduce schedule pressure,
and still meet 100% MC/DC safety requirements.  An opportunity
for a tool vendor here.

Me thinks an updated definition of MC/DC is required.
