contents The aim of this paper is to confirm an inequality predicted by Isaacs and Navarro in 1995, which asserts that for any $π'$-subgroup $Q$ of a $π$-separable group $G$, the number of $π'$-weights of $G$ with $Q$ as the first component always exceeds that of irreducible $π$-partial characters of $G$ with $Q$ as their vertex. We also give some sufficient condition to guarantee that these two numbers are equal, and thereby strengthen their main theorem on the $π$-version of the Alperin weight conjecture.
