It depends on the resources on the system, and if you plan to transport the
presentation to another system, or to many systems via CD, all bets are off.
PowerPoint doesn't manage to a timeline, so the speed of the processor, the
amount of memory, disk speed, available disk space, and contention from
other running applications, will all have an impact. If the presentation is
never going to run anywhere but on your system, you could just time it by
the wall clock.
