But shouldn't be server keep a list of KODed clients and ignore them, as per
the docs?

Is that in minutes, as in the cumulative average query rate over the last
(hour? day? week?) unit period of time?

I assume that means that any two packets within two minutes of each other
trigger the discard/KOD?  If so, isn't that overly restrictive for ntpd's
own 64-second initial query interval?

Sorry, just trying to make sense of all this.  :-)
