Indicators of the Effectiveness of Future Kambo Treatments?

[Alan3.1415]

I posted this question before, but somehow it disappeared.  I hope this question isn't somehow inappropriate.

Q. If a person has had one or more treatments with kambo, given the results of these treatments, are there rules of thumb that indicate the likely effectiveness of future kambo treatments?
In other words, what sort of guidance for future kambo treatments is provided by the earlier results a person has had?
When and how can you tell that future kambo treatments either will or will not likely be effective?
