Not saying that yours is not a good product but there are issues with some of your claims.
Sorry for the misinterpretation on the Fourier Transform. That is the more sophisticated way of doing it rather than other methods that compare the generated signal to the applied, or the inverse of monitoring the current differential. We have done all three methods but have not found them to be significantly better than the current compensation that we use.
>- welcome boost in their body vitality in as little as 15 minutes.
that is actually common among zappers depending on the individual. Some zapper sellers claim a boost in as little as 3 minutes or even 1 minute. I am not sure just how much boost they provide or how effective it actually is in the long run.
>- the rise in the pre-zap and post-zap Body Tester numbers.
The flaw in this is that the microbes could be just stunned and recover a while later. That is the same flaw that is observed with the Synchrometer.
Any claim such as this should be verified in actual before and after cultures to show specific microbial densities as measured in CFU ( colony forming units ). This quantitative analysis is the gold standard when determining that actual efficacy.
While feeling better is important, the ultimate goal is the elimination of pathogenic microbes that are causing damage.
I would love to see the results of the jar of pond water test. The truth is that if you do not have success with that, then you surely can not expect to kill microbes in a more complex environment such as in the human body.
