The main point of this note is to provide a simpler and shorter proof of the result on efficiency in Olaizola and Valenciano (2017a) based on a result on efficiency of weighted networks in Olaizola and Valenciano (2017b). Additionally, this shorter proof allows to refine the result by establishing new conclusions for the zero-measure boundaries separating the different regions of values of the parameters where different structures were proved to be the only efficient ones.
