I agree. First time I just kinda winged it and hoped I got where I wanted to be. I was struggling to get everything as near to perfect as possible and after reading some on here. I rdwhahb'd it and loved my results. Get close on flavor and target the pH you want. After that, sample and plan out the profile for the next brew or the next iteration of that same brew. I use RO, so close to distilled. I have all the listed additions available to me, and really only ever use 2 ot 3 plus lactic acid if necessary. I don't feel that I hit the Munich or the Munich boiled profile dead on, but close enough when talking about the tiny additions RO or distilled need. After several brews with it, I would not start a brew day without thinking about Bru'NWater again. Just my $0.02
Edit to add: the important thing is to get your inputs correct: volumes, weights, colors, etc
