The basic idea is that one computer matches are not very informative.  You have
two
choices:

1.  Ponder=on.  Engines can "steal" time from each other since both will be
computing most
of the time.  Unless one is unlucky enough to not have anything to ponder.  For
that move, the
opponent runs twice as fast.

2.  Ponder=off.  This might cause poor time utilization as it is an unnatural
way to run and
is not always very well tested.

Either way causes problems.  Moral?  Use two computers or else don't pay a
significant amount
of attention to the results.
