I've done both, not much of an answer I know lol. I guess it all depends on how badly you need the carbs, if that one cheat meal does it for you then I say let that be it. Sometimes I have gone two weeks before a carb-up and done the good carb/cheat meal way. I would have to say though that I prefer the one meal as it is too easy (for me) to get into the habit of wanting carbs all the time again and continuous carb meals would be too much for me on a standard day 7. Hope this helps somewhat.
