Thanks for this. But I would like to make some additional suggestions.  
There is no need to use multiple pools. You only need one. Pool works by 
using the minclock and maxclock values to work out how many peers it 
needs to add and keep track of. minclock is the minimum amount of * and 
+ peers it should keep, and maxclock is the maximum amount of total 
peers including the actual pool itself. Also the local clock has been 
deprecated in favour of orphan mode. So I would suggest something like 
this instead:

pool 0.freebsd.pool.ntp.org iburst
tos minclock 3 maxclock 6 orphan 6

This will fire up a pool association and then add 5 peers from that pool 
and keep a minimum of 3 in * or + modes. If any become unreliable it 
will add more according to the min/maxclock values.
