Mina I was just relating to you what was told to me by Freddy.
Annealing will soften the metal if done correctly and it appears if its done can enhance the performance of vibration as Freddy has stated in the video for Proto 7.
Also there is personal creativity that can be applied to enhance the operation of the cell you will make as long as the fundamental principles of the system as it works are enhanced and not degraded. (certain other methods of building were also brought to my attention IE:epoxy laced with ferrous oxide method).
So the question is still the same, has a simple single pair test be done to confirm the enhanced ionized gas and production. Before anyone were to spend and possibly waste hard earned dollars on certain processes. (anyone else other than Freddy in a video?)
Also a quality seamless tube when made seems to undergo an annealing process and this may have to do with the manufacturer that made the tubing.
Meaning I'm pretty sure all manufactures may have slightly different processes although the methods are pretty much the same.
Freddy told me he purchased his tubes from onlinemetals.

Further probing into this specification tells you:
All material is to be furnished in heat treated condition.This tubing has basically undergone some annealing to attach this specification quality to it.
It will be best when you purchase your tubing to understand what it is you are buying, so pay attention.
Annealing may be a waste of dollars if the metal has already undergone an annealing process.
