Yes, each frequency is checked only one time.
From the document "GUIDE Scanning - Click Me.pdf":
Here's how biofeedback works:
When the body encounters stress, it alters its own electrical fields through the autonomic nervous system. The results are changes in skin conductivity and heart rate.
If I deliberately lie to someone, it creates stress in my body, and the results of this are easily picked up by a polygraph. There’s nothing the subject can do to prevent this since the autonomic nervous system is not under conscious control.
And it doesn’t matter how slight or how minute the amount of stress is – the body reacts just the same.
So if you input an ultrasound sweep into a subject’s body, and one or more of its frequencies produces a sympathetic resonance from, say, a pathogen or a parasite, the subject will always have a low-level stress reaction. This is picked up immediately and recorded by Spooky Pulse’s heart rate monitor.
When the sweep is done, Spooky Pulse will then go through its list of “hits” and, depending on your settings, may sweep carefully around them to find the exact frequencies which produce these tiny stress reactions.
The final result will be a list of frequencies which can be saved as a program and used to deal with the problem effectively. Because now you have the right frequencies. You’ve found the truth —without taking out a second mortgage.
