I run a script every minute on my firewalls that calls "ntpq -p" on my
internal ntpd servers to detect failures and re-route the trafic
accordingly. This generates a lot of hits.
New users who runs ntpq or ntpdc, etc. manually often to get to know
their system better also generate a lot of hits.
I would say make sure no human or script is generating those hits (quite
high I know). I don't know, maybe use lsof (along with the client socket
number) or authd if posible at all with ntpd to find out at least which
user is causing those hits.
Otherwise, you may be facing a hard time trying to configure ntpd properly
to find out in the end that a script or human somewhere was causing those
hits. It doesn't mean you can't try to fix ntpd config quickly before
Bottom line: do not worry to much about internal hits, they do not require
any ISP bandwidth nor any important resources on your machine ;-)
