Mostly, I think, it would be knowledge that a specific pathogen is very hard to kill or stealthy. In this case, the user would run a specific program for maybe two or three days, maybe had a herx reaction that is now dying down, then wonder if the pathogens were dead or had "morphed" so they were just off-frequency.
How to set is: Go to the Settings tab, and in the Wobble box, choose which Frequency Wobble is desired and then load that to the generator and run. More information about this is found in the Technical Guide portion of the User Guide.
