I've seen a lot of people quit RBTI, but I think that's because they get hung up on other people's best practice, thinking that the best practice they tried was RBTI itself -- which it isn't, and never is. RBTI is a theory and a set of numbers representing perfect health. RBTI can be used independently of any 'best practice.' You can use the numbers to test any health program, and likewise, I really believe that the 30 minute drinking schedule is not the only solution. There's more than one way to skin a cat. That said, I've found supplementing the proper calciums according to the urine pH to be invaluable, and getting the urine and saliva pH into line is one of the most straightforward things in RBTI that can easily be added to a person's lifestyle, whatever they're doing.
I must say that his thought is compelling. Most RBTI people are aware of the instant squabbling that breaks out when two or more start discussing the details of how to follow RBTI. The quoted writer seems to be saying that once you recognize the value of the theory then you should use your test numbers to figure out if your own "best practice" can do the job. My mind flashed back to a few months ago when a gentleman who I consider extremely RBTI-solid told me that he has his clients drink 8 ounces of water when they first get up. "Yes," I fessed up, "That is what I do, too."
The funny thing is that when someone innocently asks me how to start their daily water drinking regimen, I tell them to drink 4 ounces when they start. After all, that is what it says in the literature. And, yes, I tell people who inquire that they should alternate the 4 ounces of plain distilled water with 4 ounces of lemon water each half hour. What I don't say is that I, myself, often don't. Hey, I have a life---and it comes first, RBTI second. If I am hunting, fishing, or working, I do the best I can.
Don't get me wrong. I make my lemon water each morning right after refilling the distiller and by the end of the day both lemon water and distilled water are gone. I do a quick check often enough to know that it works for me.
In my mind, the "RBTI rules" are more accurately "RBTI rules for retreats" where someone else is keeping an eye on details. Your mileage may vary.
