I'm hopeful that I'm on the right track for my efficiency problems being from my crush but one thing I noticed in my log is my numbers show the efficiency to go down from pre boil and starting. Looking at BeerSmith it looks like nearly all the numbers I captured show the efficiency into fermenter to be lower than the efficiency into boiler. Is that normal? What issue would that indicate? I assumed that it would remain the same or close to it after boil but in some cases I see a drop of 5 to 9%.
