SO i want to know if i'm understanding something. SO I brew a recipe and lets say my OG is set at 1.054 based on a brew house efficiency of 79. But I end up with an OG of 1.059 because of new and impreved fly sparging. Does that mean that my Brewhouse efficiency for the next batch should be set at 85? I have really noticed increased OG's after switching from cooler based mashes and batch sparging to direct heated and recirculating mash and a slow (45 mins) fly sparg.
