I love the software too. It really is great. Only about a month ago did I actually figure out all it could do and I had thought it wonderful before I went fiddling with options that I'd never touched before.
Rotten, are you talking about the BU:GU when you mention balance? If so, then each different style of beer fits a different balance range. Just know that a 0.5 should be something very balanced. IPA's are over 1.0 and APA's can be up to 1.0. On the flip side, malty beer styles can drop wel below the 0.5 mark. Just depends on what you're going for. I've seen the formula for figuring balance somewhere but can't find it just now. It has to do with OG versus IBU, from memory.
