This is not about simulation tests, but more likely about industrial processes.
If you are already paying $60K per year to your QA technicians, it does not matter if the rule fires once per hour or once per week. You want those guys to investigate every incident. Most of the times there will be false positives but every other month QA will catch enough minor defects to pay for itself. The real benefit though, is to catch the bigger multi-million-dollar-issues that come every other year.
(I'm taking some rigorous approach here. By intuition it seems to me that Rule 5 should generate more false-positives than other rules)
