The first time I used BS I just used the defaults for one of the preloaded set ups, each batch I made I took good notes and measurements of volumes and losses and then re-configured for my system set up.
You really have to brew a few batches to get the software dialed in just like learning how your system works to dial it in. Once you get that the software does a great job!
