What exactly do you think is wrong there?

Actually the quote also says " (see Figure 3)."

As the file name http://www.ntp.org/ntpfaq/ntp35f-init.png might suggest, the
version used was xntp-3.5, and I apologize for the lack of a legend on the X

As the sources of the FAQ also say:
 <imagedata revision="2000-09-28" fileref="ntp35f-init.png" format="png">

it's obvious that this was almost sevel years ago. However, as HP still ships
xntpd (AFAIK), that numbers may be valid still.
