slow then it corrects.
Phase noise is rather rapid in nature that is why it typically
occupies a large range of frequencies. Typically is a cycle to cycle
difference of the oscillator causing it to scatter noise all over the place.

I fail to see why doing the same thing over and over and getting the
same results every time is insanity: I've almost proved it isn't;
only a few more tests now and I'm sure results will differ this time ...
