Does this look sane to you for a Raspberry Pi with a
Sure Electronics board and PPS enabled? It looks fine to me,
I just want to confirm that people more experienced than me
see it the same way.

I do not see any "kern", as described by some tutorials. Should I
worry about that? Cf. eg.:
http://www.satsignal.eu/ntp/Raspberry-Pi-NTP.html
The relevant section of /etc/ntpd.conf is:
server bevtime1.metrologie.at iburst
server ts1.univie.ac.at iburst
server ntp.liwest.at iburst
