My SF doesn't go beyond 2-3 anymore either. Especially since I use infused oils to color my soap so there will be a grams added onto that. My cleansing varies between 6-12 depending on what else is in that recipe. I only look at that, and the longevity. Everything else is anything goes lol
I make both vegan and lard soaps. I'd make tallow soaps if I can source it. I too haven't eaten any soap in maybe a few decades. I do once in a whole brush my teeth with it, does that count? Lol
Sorry for taking so long to answer
