3711 can sometimes take a long time for those last few points. If you're bottling with an average amount of priming sugar, you shouldn't have to worry, an extra point or so won't create bottle bombs. But if you're like me and want your saison extra bubbly, I'd give it a week or even two after you think it's done, just to make sure. I usually carb mine pretty close to the limit of what the bottles can handle, so if the fermentation is still inching along on those last couple points, I end up with a blowout or two on the weaker bottles...
