Which in no way contradicts the statement that "jitter specs mean very little". Note it doesn't say, "jitter means very little". The specs are the problem, as apparently there isn't a standard way to measure them and compare them, so you can have 2 different measurements from the same equipement and both are "ACCURATE"-just not done the same way.
thanks, couldn't have said it better myself.

I would only add that the spectrum of the jitter is probably more important than the magnitude, and there have been no studies to show which spectra are more objectionable for listeners.
