I attempted my first decoction on Saturday, and after a grueling 4-hour mash process, and 60 minutes of the final conversion rest at 159f, I was still testing positive for starches in my mash. I decided to proceed with the boil anyway, and my efficiency was great---85%. But I'm wondering: since there were still unconverted starches left in the beer, is it possible that at least some of my gravity points are coming from unfermentable starches?
