If you want to know what goes into the calculation of effective jitter, check out www.jitterlabs.com or the downloadable assets at https://abracon.com.

I've seen this testing in action for various industry Rb and OCXO based popular offerings and the test methodology and results are a learning experience and surprise in and of themselves.
