If you mean to imply that BFA coverage of code proves that no bugs
exist in the code covered, I don't agree.  BFA proves that the code
was touched, not that it works.  A lot of code is data sensitive
in it's behavior and bugs may only appear with certain data, so
it really is not a reasonable conclusion that there are no bugs
left in the 85% which has been covered.
