I put a recipe in and got my grain bill and such but it seemed really high. After going through the recipe, I noticed I did not change the efficiency of my brew. How can I have those numbers change to correspond to new efficiency without having to go through entering all the information again. I know FG target and percentages of ingredients. Everything I tried including changing the target FG doesn't make the weight change nor the total FG calculated. Any suggestions before I start over?
