Depends on what you mean by incredibly rare. It's happened to me more than once.

You kind of made my point here. If you set it too low to even get included when the high fee transactions have been decimated during the last hours, then you're in trouble. But if you go with a fee has been included at many different times during the last hours/days, then you're pretty safe even if the miners are unlucky for a while.
