The application of V/V_max statistics to gravitational-wave cosmology aids in our understanding of compact object parameter evolution, particularly the redshift and mass distributions of binary systems. Transforming from a distance-dependent to a population-dependent diagnostic provides a direct pipeline for testing various gravitational-wave source distributions. Through this framework, we find support for a binary black hole source redshift distribution. Furthermore, we find that the methodology remains robust under minimal assumptions about the mass distribution, with negligible effect on values for individual events. Finally, we compare this methodology to Hierarchical Bayesian Inference, and why can act as a powerful tool for population statistics with O4 data.
