no need to apologize. I think I understand where you are coming from. While I don't think I can answer your 'bright line' question, I can give you some examples of specific conditions that I have moved beyond.
one easy one... dairy intolerance. plagued me for years, and tried everything before rife. after, or as a result of rife and related treatments... I eat dairy every day. that was a huge change in my life. of course, its not as simple as saying that there is one frq for dairy allergies/intolerance... instead, you have to treat the real underlying factors to reach a resolution. same is true of every chronic health condition.
this is just one example... like I said, turned my life around. hard to summarize that.
