Not sure yet why my rendering was so much longer, but it seems a strange coincidence that my time had similar digits in a different order: time=0:18:57.00

Apparently, you calculated the parameter file using arbitrary precision math. I forgot to include the mathtolerance entry in the parameter file, which would force the use of conventional high-speed math. The difference in the appearance of the final image is barely discernable. The similar digits is a coincidence. Jim M.
