I'm kind of confused about how superfatting is calculated and done. I've seen lye calculators that have an area to input SF % and then amounts of oil (in % - must equal 100). So if you want to make 5% SF and you want 35% CO, 35% OO and 25% lard, 5% castor, & you plan to use 500grams of oil, the only difference between 5% and NO-SF is the amount of lye used.

Method 1
I've read that people mix all the oils then add lye water and then EO's at some point prior to trace.
Method 2
I've also read of people mixing 95% of the oils (maybe in this case leave out the castor, or Kokum butter in another recipe) with they lye water and when it gets close to trace add in the castor or Kokum butter & EO's. This way you are garunteed to have a specific fat non saponified.
I'm wondering if one way is better than another or better for a specific purpose. Is there any harm in either of these methods?
Is there a better way to clear this up/explain the process or are the above methods proper?
