As a new all grain brewer, a couple of things to help me calm down about my mash... Display the boil gravity in the recipe view of the brew session. I always go back to editing my recipe to note what I should be expecting. Emergency snafu calculator. If I miss my gravity a little calculator to help me figure out how much DME (etc) I should add to get the gravity where I expect. I currently go back to the recipe edit and lower the efficiency until it matches by measured gravity, and then add DME to the fermentables until the gravity comes back to where I expect. Thanks for the site, it's the only way I'm making halfway drinkable beers.
