It kinda depends...like, if I have a floral FO I will try to do it "full water" at 35%. For things I know don't really accelerate trace, or if I know I'm not needing time to do color, I can discount. I've gone as low as 25% water-to-oils and been ok, but that's after doing the same recipe several times, over time, and just decreased the water little by little.
I've also had rainwater sploosh into my lyewater and had the soap really turn out sucky because of an unknown water content. Like, probably way too high of water %
