Well, you do have to feed, er, update it at least every six months if you don't want to be left with an unholy mess to clean up.
I'd advise every week, within six months a lot has changed and you may end up with messed-up inconsistencies.
Six months is the max that's supposed to be supported. (Longest no-update period I've ever sorted out was twelve months. Possible, but time-consuming.)
