Take a gravity reading about every four days and see if the gravity is still dropping. With D47 I suspect it will go a bit further. I'm guessing your OG was about 1.07-1.10 or somewhere around that, so D47 will take that dry as a bone since your PABV is about 12% and D47 will normally run to 14% ABV tolerance, although I have a batch of Cherry Cyser right now that is sitting at 17+, so it can go very very dry based on the recipe you cited.
Hope that helps,
