The Factor[] is processed *after* storing in the database (.log or .rrd)
and is only used when generating the graph image.  So, the logfiles will
always hold the 48000 values.  If you run in RRD mode, MRTG does not
generate the graphs, and so it never uses the Factor[] at all.

I think there may be a bug in the later version of MRTG that ignores a
decimal Factor[] when running in native mode and generating the graph.
