We simulate dc V-I data using Gaussian distributions of depinning currents for the mixed state of a copper-oxide superconductor and subsequently submit the data to a critical scaling analysis. Though the simple model for simulation assumes no phase transition for the vortex matter, the generated data exhibit a collapse matching those in the experimental literature. The resulting would-be critical parameters depend on the simulated sensitivity level, reinforcing doubts concerning the utility of the scaling analysis for these systems.
