That would have been a great episode! I can see it now:

Commander LaForge: "Ensign...Why would you randomly reverse the ship's polarity?"

Ensign Everyman (blinks and thinks for a moment): "Well, Commander LaForge, if it were done regularly, the reversal would have to become a part of the maintenance procedures and schedule for every ship in the fleet. The optimal period for reversal would be different for every every class of ship. Every ship class—and variant—would have to undergo a StarFleet Maintenance Procedures Review and a period of testing before they could do it at all. And that could take years!"
