I think you misunderstood my initial criticism with respect to frequency accuracy and it's effects in such cases. Which was not to discredit the value of the standards used to identify and repeat specific treatments. But rather... the inherent value of the accuracy measurements used to promote products in the competitive market.
The advantages of frequency precision can only justified when it falls outside the intended target range. And so while such claims may be impressive in terms of build quality and craftsmanship, it remains that any additional resolution within the intended target range can never be substantiated. And so it's important to establish such facts so as to avoid leading people into the false sense that they are somehow getting a better device in terms of healing potential based on claims of higher accuracy alone.
IOW. If a generator is reliable and falls within 1/4% of the target frequency, then it's very unlikely that anyone could justify the claim that tighter tolerances could ever prove better in terms of treatment effectiveness.
Hope this helps
PS. I purchased a Spooky2 device to test it against a simple Beck Blood Zapper and where it was an affordable way to enter the world of multi-frequency zapping.
