Right all those things need to be controlled if doing high end nut-testing.
Most time nuts already know enough not to shake their Osc or tweak its Power
supply etc when taking ADEV data.
What is often left as the major error source (that can most easily be
controlled) with a careful setup is delta temperature.
and most also know that temperature needs to be controlled in some way
especially when getting the most from say a GPSDO.

You can of course use the ADEV math function for anything, but MY
definition of "true and accurate ADEV numbers" must include a set up
that gives repeatable results.
If you test is done over different or unknown temperature changes that
have major effects, then I'm calling that poor ADEV data (taking).
Then you had better control acceleration (gravity/shock/vibration),
voltages, humidity, pressure, electromagnetic fields, et al, if you want
validity. Again, what makes temperature a unique case?
