  The frequency distributions of sizes and fluxes of supra-arcade downflows
(SADs) provide information about the process of their creation. For example, a
fractal creation process may be expected to yield a power-law distribution of
sizes and/or fluxes. We examine 120 cross-sectional areas and magnetic flux
estimates found by Savage & McKenzie for SADs, and find that (1) the areas are
consistent with a log-normal distribution and (2) the fluxes are consistent
with both a log-normal and an exponential distribution. Neither set of
measurements is compatible with a power-law distribution nor a normal
distribution. As a demonstration of the applicability of these findings to
improved understanding of reconnection, we consider a simple SAD growth
scenario with minimal assumptions, capable of producing a log-normal
distribution.
