This may be a seem to be a silly question however I can't for the life of me find the answer to it. let say you were going to use 6% FO in your formula and you are starting with 100oz of wax, does this mean A) you use 100oz of wax and add 6oz of FO for a total of 106oz or you use 94oz of wax and add 6oz of FO for a total of 100oz or in other words, do you calculate of FO% on top of or within any giving wax amount?
