Heavy ion collision physics has made remarkable progress in understanding the properties of QCD matter through sophisticated hydrodynamic and transport modeling. However, as we extend these frameworks to lighter systems (O-O, Ne-Ne, etc.), we often carry forward assumptions validated in Pb-Pb collisions. In this talk, I want to re-evaluate two assumptions found in hybrid approaches modeling approaches: (1) the use of a fixed thermalization time $\tau$ independent of system size (and collision energy), and (2) the prescription of dependence on nuclear densities.
