In reality, no pen test that I've ever seen can really make much of
a statement about the security of a system. This is because (a) your
results only reflect defects that are known today, and new ones will
be found and exploits developed tomorrow, and (b) your results only
apply to the configuration of the system at the time of the test. Any
simple change, even as much as adding a single user, invalidates your
testing.

We put an extensive disclaimer explaining this in our contracts.
The value in the pen test is finding open doors. A 3-hour test
is going to have limited results in any event; it can only tell
you that some of the more obvious, well-known doors are closed.
You simply don't have enough time to conduct a thorough test.
