Modified how elapsed time is checked in one of the tutorials

For some reason, on my PowerMac G5 at home, sleeping for a given amount of time
can result in elapsed time slightly less than what was requested.  Therefore,
when checking elapsed time, I multiplied the expected time by a factor that is
very close to one, namely, 0.99996.
