But, as I've found, only if "The Internet" has predictable and stable 
ping times.

When your ISP is so clagged up with traffic, or as a home user you get 
"trottled" during the day, then the ping times wander between a few 10's 
of uS, and often over 1.5 seconds at random, ping to ping, even NTP 
can't cope with that!
