ntpq peers - poll column

Deep in the ntpq code is this line:
  poll_sec = 1 << min(ppoll, hpoll)

poll_sec is what gets printed in the poll column of the peers printout.

hpoll is the local polling interval used to determine when to send the next 
  It is also used to schedule DNS/NTS retries.
ppoll is the polling interval from the last reply received.

Does anybody know why the remote polling interval is interesting?  or rather, 
why I shouldn't "fix" that?

I think it was useful with peer mode that we removed a long time ago.

Context is that I'm trying to tune/cleanup the DNS/NTS retry logic to reduce 
log clutter.  I was using the poll column to monitor the retry timer but was 
getting some confusing results.

These are my opinions.  I hate spam.
