Talk is cheap, yet time consuming, and proves nothing.

Send this list some ntpviz output showing this driver adds value,
otherwise this discussion is a waste.  If you can prove added value
then getting it ready to include will just require the obvious grunt work.

I have a driveway to shovel and hours to drive, so my answers will
have to wait.  I hope to see nice plots when I return.

But one point worth noting:

Which is aweful.  If you can't get it under 50 ns don't bother.
