The asymptotic scaling behavior of the Kuramoto model with finite populations has been notably elusive, despite comprehensive investigations employing both analytical and numerical methods. In this study, we explore the Kuramoto model with "deterministic" sampling of natural frequencies, employing extensive numerical simulations and report the asymptotic values of the finite-size scaling (FSS) exponents, which deviate significantly from the previously reported values in the literature. Additionally, we observe that these exponents are sensitive to the specifics of the sampling method. We discuss the origins of this variability through the self-consistent theory of the entrained oscillators.
