I dont look at the numbers at all, for me its a bit like painting by numbers and therefore never getting to grips with the actual art of painting or making good balanced soap, although I know that is a very personal thing. I had found that just because the numbers say this or that the soap itself does not always match that, its all a bit of a theory. Yes for the very new beginner it is a guide and a starter but after that I think its good to experiment and go for it rather than being constricted by numbers especially once you know the basics. Maybe its me because when I first started soaping 18 years ago there was no Soap calc but there were calculators for the lye and water amounts, for me maybe that was a good thing as it helped me learn and work out in practice what worked and what didn't. It is surprising the amount you learn from a failed or not great batch.
