It “crowd sources” (thx @Starlight) the appropriate individualized solution for you but gathered from everyone who listened to it and adjusts the treatment accordingly.
It’s no different than if you talked with a real doctor (A smart one that is 
) who was applying an individualized treatment based on their years of experience and hundreds of patients who had various issues that may have been similar.
It’s a smarter, updated version of the analogy I gave about fields being like a personal trainer in the no boost thread.
