My experience is also that my server runs stable with 6 st2 and 3 st3
servers. I've selected them on (short term) stability, ping time, # of hops
with traceroute and different upstream st1 server. These are my stats
(located in Europe): http://www.pool.ntp.org/scores/194.109.223.180

My theory: a st1 may fluctuate due to load, temperature changes, signal
loss, etc. which is filtered by a st2. A st2 is less popular, so a well
configured st2 only fluctuates due to temperature changes. Therefore, it's
best to have a local time source or sync with st2 :-)
