I think that the real questions that needs to be answered are:
1) How accurate is the estimated offset that the server is using at any
point in time;
2) What is the error in the calculated frequency that the server has
estimated;
3) What is the error of the jitter that the server has calculated?
There are two possibilities here:
1) The server itself calculates these values so it will have an estimate
of the error;
2) An external estimate of these errors introduces you to quantum
physics issues, the measurement affects the values being measured.
Does this restate the question better?
