A simple and exactly solvable unified model for fragmentation was recently proposed. It involved a single parameter which served to tune relative contributions of evaporation and multifragmentation to the mass-yield distribution for nuclear reactions. We have measured mass-yield curves for intermediate-mass products from medium-mass nuclei by radioactivation techniques. They are compared to the model's predictions. No choice of the single parameter is able to reproduce the observed trend. It is argued that by disregarding initial intranuclear cascading, the model is incomplete. Its advantage might lie in combining it with intranuclear cascade/evaporation calculations.
