I understand from various replies I had that I cannot measure ADEV the
way I thought I could. I am an electronics man, not a mathematician (or
should that be mathemagician?). Adding the ADEV was an afterthought and
I'll leave the development of that for now.
Just to follow up on the Pendulum presentation, here is a paper from
Staffan Johansson detailing both frequency and ADEV calculations, and as
I understand the paper they do the ADEV properly and not based on the
linear regression estimated frequency values.

This also fits my memory correct from previous discussions.
Just so that nobody incorrectly believes that they do their ADEV on the
wrong values, but it was just an issue of misunderstanding the presentation.
Cheers,
Magnus
