Right. And NTP assumes the routing delays are symmetric. But it doesn't know
anything about the delays so it has to add 1/2 the round trip time to the
possible error budget.
If you knew the server was on the other side of the country, you could make a
rough estimate of the minimal round trip time and remove that from the error
budget.
