Melt & Pour from Scratch

[Garden Gives Me Joy]

I am considering my first melt & pour soap from scratch and wondered the following.

Is it advisable to set the NaOH discount at 0% so that I can customize re-melted portions with any type of superfat (up to apx 4%) later? If I do this, I imagine I would only need to remember that some of the gross weight of the solid bar includes a small amount of non-fat ingredients.

Would this approach require me to consider more or less glycerine and or castor oil to compensate?

Should I assume that all the rules regarding citric acid to avoid soap scum, (and adjusting the NaOH accordingly) etc still apply?

Also happy for ideas re additive when re-batchnig the cured M&P base.

LOL I hafta ask, WHY?! It's challenging for starters but, more importantly, the purpose of M&P soap is to avoid using lye. By making it from scratch you defeat the purpose for which it is designed. Why not just make lye-based CP or HP?
What am I missing?

ETA: Cold process melt & pour soap base from scratch... Is it possible?

Having one's own M&P seems to offer opportunities to take on custom projects of any size and even with short notice. Furthermore, no one can say the soap is not your 'natural handcrafted soap'.

From that perspective, it seems like a sensible (manufacturing) business decision!

I have never used any type of M&P before. Am therefore happy for anyone to correct or extend my assumptions with examples or other ideas.
