Think of 77 kHz - 295 kHz like two octaves on a piano. Let's use Low C to High C. Then 295 kHz divided by 2 is 147.5 kHz. 147.5 kHz rounds up nicely to 148 kHz.
147.5 kHz will be our Middle C.
Just happens that when you double a frequency, you get the next octave of the same kind of sound. Because they are the same kind of sound, they share properties in common. Especially those things we call nodal points -- in case you wanted to dig deeper.
So when we scan LowC D E F G A B MiddleC, and we get a hit on E, we may have gotten a hit for E in the range we scanned, or the E in the next octave, which would cover 147.5 - 295 kHz.
When you play an E note on the piano, it resonates all other E notes.
However, the math for this range is not quite perfect, as 77 kHz doubled is not 147.5 kHz.
I would use 76 kHz - 152 kHz to scan, which will allow hit detection by resonance in the range actually all the way to 1.216 MHz which is only 4 octaves away.
Mind you it also goes the other way, so, you also get hit potentials via resonance for frequencies below 76 kHz.
This range is actually the default Biofeedback scan range and uses a step size of 20 so that no frequency is skipped. It would take forever to scan every frequency 1 Hz at a time.
Using a step size of 20 Hz covers the scan range in 3,800 individual scans. Why 20? Well the range a frequency can resonate a pathogen is called the MOR % tolerance range. We currently use 0.025% and 0.025% of 76000 is 19. With +- 19 Hz overlap, we can scan 38 Hz of frequency resonance with just one frequency in the center.
Hope my quick and not as well laid out description is working, very tired at the moment.
One last note. Because Biofeedback is not a diagnostic tool, and this is essentially (even your example range to a degree) a full frequency scan, you can not isolate the results to just mold.
Your body will return what it wants, and it is very hard to put a label on each frequency hit returned.
