Actually, I tried that some time back, but it didn't help a bit.

I eventually came to understand that "xleave" mode is designed to
reduce the effect of processing delays inside a server's network
stack.  Sadly, it doesn't do a thing to alleviate asymmetries.

Indeed, my current impression (someone please correct me if I'm
wrong!) is that NTP is *inherently incapable* of measuring (or even
detecting) network latency asymmetries -- the NTP protocol assumes
that traffic "comes" and "goes" with equal speed, and it has no way
to detect situations in which this is not true.
