I read all man pages, was a bit painful haha but I can read that line like English now :P

Stiil, wondering if there's any theory behind how fast these types of checks should be run. One thing is obvious, SMART is meant to expose a problem before it becomes a real problem of sorts. So, perhaps running the tests somewhat often is a good idea. But how often that IS the question.

Absolutely

You mean slow down how fast a test is being performed?
