Thanks for starting this update!
A first note is that in chapter 1.1 you are proposing a way of calcylating yield that may create unneccessary frustation. It is easier often to calculate it as the output/ input.
sometimes you only know what is coming out as product and how much you put in. The difference is waste, burnt or stored in the system. This is also a way of identifying how much material losses that you are not recovering as waste.
