Got a code reference? We are both reading the same doc and coming to
different conclusions. I already updated my peer section to reflect
your comments. See below for the latest.
Before we dive down that rat hole, do you agree with the latest peer
section, as below? If not, got a proposed wording change?

Is there a better way than I am doing?
I just copied off the pool, ubuntu, gentoo and redhat howtos:
http://www.pool.ntp.org/en/use.html
https://help.ubuntu.com/lts/serverguide/NTP.html
https://wiki.gentoo.org/wiki/Ntp
https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/6/html/Deployment_Guide/sect-Date_and_Time_Configuration-Command_Line_Configuration-Network_Time_Protocol.html
Are they all suboptimal?

Your suggested ntp.conf line?
If there is a better way, then the howto should explain why the
'common knowledge' on the internet is wrong.
Until then, this is our best guess:
# If you have no other local chimers to help NTP perform sanity checks
# then you can use some public chimers from the NTP public pool:
# http://www.pool.ntp.org/en/
# To use the pool servers uncomment the last four lines in this section.
# The iburst option tells ntpd to query the pool servers with an initial
# burst instead of single requests. This can yield better results on
# startup to remote servers.
# Notice I use the 'us' country code servers, otherwise I might get one
# pool server from Ukraine and another from Singapore. If you are
# not in the USA, then change the 'us' to your two letter country code.
# server 0.us.pool.ntp.org iburst
# server 1.us.pool.ntp.org iburst
# server 2.us.pool.ntp.org iburst
# server 3.us.pool.ntp.org iburst
