slight detour...
As a somewhat selfish/biased computery brewer/person, what has you tied to promash that other pieces of software don't do or don't do as well?
I'm working on an article that compares all the more popular pieces of software to get a running list of features and issues that people run into.
Like I said a page or two ago, I tried to use promash but it was too clunky and felt super out of date. The user interface was extremely annoying to me, and some default options (boil off rate for one, pet peeve) just didn't make sense at all with modern brewing knowledge.
I feel that something so out of date, and with how much progress has been made with modern techniques and information, that it cannot possibly be a superior product when compared to the more supported/updated options:
Beersmith, or the myriad of online alternatives like brewers friend, brewtoad, mine, or even homebrewhedonist.
ATM I use a rather eclectic list of software/spreadsheets/calculators.
Bru'n water for water chemistry/ph.
Mine for water volumes, temps, and efficiency estimations.*
Beersmith for recipe formulation/scaling of recipes for my small batches (usually do .75-2G now)
Brewunited for yeast starters (looking forward to the one being worked on by omega yeast labs!)
*working on recipe formulation and a modification of the Tinseth formula which will incorporate iso acid solubility (from someone's master thesis) and instantaneous wort gravity instead of average (idea I had and emailed Tinseth about, math seems to check out so far but still testing)
