What I learned while masterbatching oils

I made my unicorns soap and the emerald city inspired soap out of the same oils, so that I could masterbatch them.  (Meaning measuring all the oils once for both batches, and then dividing them among each batch.)  There are plenty of videos and blogs that teach you to do this.  Here is one (not mine):

So I mixed a total of 92 oz of oils.  For the unicorn soap, I weighed out the 54 oz.  In theory, there should be 38 oz left in the container for the emerald soap.  But there were only 37 oz.How did this happen?  Well, I assume I lost some oil in between containers.  You see, I put the butters in a container that was small enough for the microwave.  I measured the shea butter in a different container too, to avoid putting it in the microwave (It is supposed to lose some properties if heated at too high of a temperature).  And then I put the liquid oils in a third container large enough for all of them.Does it matter?  It was just 1 oz.   Well, I decided to run the numbers in a lye calculator.  So by losing 1 oz of oils out of 38 oz of oils  (a 2.63% of the total oils), my superfat went from 5% to 3%, so it will be slightly less conditioning.  So although it will not be lye heavy (If that happened, I would honestly cry with ugly face for an hour) it will not be as conditioning as I would like it to be.2- MASTERBATCHING OILS WILL MOTIVATE YOU TO MAKE SOAP SOONER:It was easy for me to start on the emerald city soap once I knew the oils were ready and just waiting for me.  It also put some pressure, because I was concerned of potential spills having the oils covered with something that was not securely sealed (meaning, not screw type lid)3- MASTERBATCHING OILS WILL TEACH YOU ABOUT SOAPMAKINGIf your oils are the same, you will learn about the fragrance effects,  mixing effects, gelling effects, etc.  Both batches I made behaved differently, and I could tell the effects the fragrance oils had, since my temperatures and consistencies were similar, and the base oils were identical.And lastly, It can be confusing to masterbatch when you are making different sizes of batches.  It helped me keep things clear to print a recipe for both batches, and then individual recipes for each batch.
