One thing I’d like to add concerning software to determine water mineral additions: the first time you brew with certain preset additions recommended by the software designer will probably not be the final solution. Like IBU, the numbers are a reference point to start from. Each of us is different in our preferences and perceptions of our beers.
For example, 40 IBU calculated by a beer design program of choice in the same grain bill to a bitter ratio of .6 is perceived by one brewer as plenty of hops but for another as not near enough. CaCl and/or gypsum can affect this perception.
Likewise, the preset additions in the water software may not give the final desired results. It’ll get you started and definitely in the ballpark, but a bit more of this or a bit more of that, discovered thru trial and error, to nail down a profile to your taste preference will probably be required.
