Have you tried doing the same prediction using the last 4 weeks growth or slowdown of sales, and applying the same growth/slowdown to the future? It doesn't make much sense to assume that sales will remain constant.
Of course it doesn't make sense that growth/slowdown will remain constant either, but it's probably a closer estimate...
