  The value of the dynamic critical exponent z has been studied for
experimental two-dimensional superconducting and Josephson Junction array
systems in zero magnetic field via the Fisher-Fisher-Huse dynamic scaling
analysis. We found z~5.6, a relatively large value indicative of non-diffusive
dynamics. We extend this work here to simulational I-V curves that are also
found to be characterized by the same large value of z.
