I hear your frustration!It is ridiculous to suggest that low end of the recommended cleansing number is 12.
It's good to keep in mind that "the system" is comprised of values intended for a "best case scenario" and included as "recommendations", i.e., not written in stone, so to speak. Whatever calculator you use, it's best to consider the recommendations as guidelines for whatever formula you're trying to create.
There will always be exceptions to the recommended values. That you learn through experience.
HAPPY SOAPING!
