You're passing colonies with butyric acid? Interesting indeed.
What else are you doing in your protocol? Diet? Antifungals? Enemas? Flushes? Have you done anything or shifted a major routine recently?
When I was spontaneously killing colonies everday I suspected that imported butter was playing a role in the process. I was enjoying at least 6 tablespoons a day. It was Smjor, a deep yellow butter from iceland with an amazing flavor. No doubt much higher in butyric acid than other butters.
