Where these proportions come from
Our own construction: a firm base, because the abrasive goes in at trace and softens the bar. The abrasive itself is an additive, not an oil.
A canonical formulation: the proportions the craft has settled on for this kind of soap. Not transcribed from a document, and not copied from anywhere.
