The problem with a rule-of-thumb approach such as this is that it does away for the requirement to apply engineering judgement.
For example, the exposed cores. Are they exposed because they were installed sloppily, and therefore might remain just as they are reasonably safely; or is is because they have pulled out (whether by gravity or some other force) and might get pulled out some more.
