I'm not understanding something - nothing unusual there :)

I thought that "run time" was the total time it took to
complete the amdump run.  I.e. including the estimate
phase, the dumping phase, and the taping phase.  Further,
if there were no parallelism in the phases that it would
be approximately the sum of the three phases.  But never
shorter than any of the single phases like your "dump time"s
each much longer that the total "run time"s.

What am I missing?
