Clarifications and observations are made regarding Segletes equation of state, in response to recent comments and criticisms. A theoretical justification for the form of the equation of state is laid out in more precise detail. The model is shown to produce high-quality fits to shock, as well as cold-compression data, especially when accounting for the experimental variability of the model input parameters. The falseness of the correspondence between the volumetric and vibrational spring constants for an atomic lattice, previously inferred from Segletes equation of state, is proven by alternate means. The non-Gruneisen behavior of aluminum is addressed, and a brief note is made regarding the nature of isentropic transition.
