275 kHz - 550 kHz is an octal harmonic range. Your scan fell short ending at 450 kHz.
The step size that needs to be used to not leave holes with a scan starting at 275 kHz is 50 -- where the MOR tolerance is 68.75 Hz. You could use 70, but it does not evenly divide the scan range.
Biofeedback is not a diagnostic tool. Reverse lookup is only as good as the Database and is only useful in hindsight.
The first few scans may pick up the more noisy pathogens at first. The ones that cause the most problems are already really good at evading the immune system.
Continue to apply the results and rescan every 5 - 7 days.
