Am I missing something? I didn't see the multiplication by 1000 and the above numbers don't show any trailing zeros or truncation of precision as I would expect if the number had been multiplied by 1000. Although, maybe the multiplication occurred before the division by the number of runs. It just looked suspect to me.
