Well yes, I'm aware of that and it was this extra latency that I wanted
to ascertain. What puzzles me is that each time the jack server is
invoked, it will need a different amount of latency compensation even
when no other parameters have changed.

I'll read that thread and it's links again, but IIRC they don't hold
the answer to my query.
