This is why it is important to remember that all polarity designations are arbitrary. What is important and non-arbitrary is how the physical relationships and connections affect the movement of energy.
From what i understand i agree with most of what you said, and that's why i criticize the importance of using "100% positive offset" with dc current (when dc current charged particles/waves can only flow/pressure from one side to another) and the importance of using more electrodes of one polarity than of another (when charged particles/waves will spread the same way from one polarity to another). What matters is how the charged particles/waves spread in the body and how they can affect the human cells and the harmful organisms.
So what do you have to say about the claim made by Parazapper that it is important to use more electrodes of one polarity than of another ?
