Well SY without testing its hard to say. But looking at it from a strictly mechanical point of view if the fins are vibrating and transfering the vibrations to the chip and the chip vibrates and causes distortion then its likely(<---keyword) that vibrations of the chip causes distortion.It dosent distort when i dont finger it (hehehe) so at the moment all i have is the cause and effect to base anything on.
Having been in QC for the majority of my life i am not stating that it is the only possible answer to the question.I have learned (the hard way) that only extensive testing trying to re-create the actual in use conditions with a scientific approach to data collection is the best method.But even then there could be some factor that wasent considered.

As things to look at, consider integrity of connections and inducing oscillations by injecting noise and stray reactances in a train of pulses. Or a bad chip. The behavior you describe is quite atypical.

Konnichiwa,
I did some experiments, but nothing sufficiently structured and complete. Anyway, one we get to 10ppm or lower audio measurements become an expensive game.
AFAIK - Yes.
It works relaible but not neccesarily with too great accurcay. It's a question of application.

From my days of measuring fluorescence from earthworm giant axons (yes you did read this correctly), I learned about the sensitivity of electrical components to mechanical stresses. Just bending cables would change the resistance enough to affect my data. Of course the currents I was measuring were extremely small.

The resistance would settle back down. I can't say that it came back to exactly the same level. Bending any cable will cause microscopic cracks in the copper that are detectable on electron microscopy. This could affect the conductance.
It was through these experiments that I actually learned the importance of good cable construction.
