In the present global model for violent dynamical systems' relaxation, which is based on both the virial equation and an additional equation for the potential energy's approach to equilibrium, the central region of the system is shown in light of very general arguments to shed mass to an extended envelope in the collapse episode. Specific upper and lower limits for the mass in the core can be calculated. The standard Aarseth N-body code was used to describe mutual interactions, and comparison with numerical experiments yield agreement with model predictions.
