well, until very recently, i'd stick to it for a week, and then go off for a week or month even, but it's been 2 weeks now, and i only cheated once the first week, and twice the second, and even on those days i might call it little strays, since it was only over by about 10 carbs. so I clicked the once a week button. hope someday to be able to say once a month. that never, doesn't even seem like a remote possibility.
