When you follow the breadcrum trace to the paper for control algorithm 
theory, the ADEV intercept point is traceable to a different concept 
with different noise-behavior, in which the method worked, where as 
re-applying it to the noises of packet networks may not be the best of 

With all the theory available, it just doesn't necessarily apply to the 

BTW, the ADEV intercept-point was done not by Dave Mills, but he refer 
to a paper by Judah Levine.
