Brian,

I know this is supposed to happen, but I recall seeing behaviour some time 
ago where a server with a little more jitter and much more delay was 
preferred, almost as if it was the jitter/offset which was the measure 
rather than offset itself.  I ended up adding a "prefer" qualifier.

Cheers,
