I downloaded it a few weeks ago and am still getting it set up. I'm hoping to have everything ready for the start of the new year.
My biggest issue has to do with lye amounts. Right now I calculate everything in a spreadsheet with the SAP values provided by my suppliers. As a result, I've had to do like lsg; I tweak the SF in SM3 until the amounts match my files. This gets complicated because I also test my NaOH for purity, and I can't set a purity % for NaOH in SM3 (like you can for KOH).
And then comes the issue with duel-lye bars. I have to use the Cream Soap settings, but again, I can't set the NaOH purity. It's taking a lot of fiddling to enter my bar soap recipe so that the amounts come out close to what I'm used to.
