I have been having some issues with efficiency being too low and after reading a few posts in the AG forum I begin to wonder if I'm using BeerSmith incorrectly. What value should you put into BeerSmith for your brew house efficiency? Is it what you think you can do or is it where you'd like to be? It seems like each time I adjust the values down to be closer to what I get my results also go down. I'm wondering if I should just set it to something I'd like to hit like 70 or 75% and then keep working on my procedures to try and reach that goal.
