I only brew once before posting... however....
Usually what happens is I make a recipe and decide I don't like it for one reason or another, so then I reformulate it and try again. That narrows it down, but usually there's still something here or there that's a little off. I try a third time, if necessary, to get exactly what I'm going for. Then, if I'm still a little off, maybe I'll notate how to do it next time, but not even bother brewing it before posting the recipe. Afterall, if it's a tiny change in formulation, you already know what you're gonna get...
For instance with my Hefe Candy, I wanted a honey hefeweizen. I brewed it and it wasn't that great, so I tried again. And again. Finally, I got what I believed to be the best you can get with a Honey Hefeweizen. It has nothing to do with the style guidelines of course, but it has everything to do with the nature of the ingredients. For instance, to get a good honey flavor, you need a good amount of honey. But honey ferments dry, making the beer kind of watery and alcoholic. So then you try using more brumalt and cutting back the honey, and try again. Finally, I cut the honey down to only a nominal amount, cranked up the brumalt, and mashed high for a really sweet beer. And that, to me, is the best tasting beer you can get if you are intent on combining honey and WLP300 and trying to meet peoples' expectations as to what a honey hefe should taste like... because a thin, overly-dry beer just wouldn't meet my expectations for a honey hefe.
Of course, others can feel free to disagree.
