I believe Soylent has a pretty good idea. They know what changed in their formula, they know the difference between the products receiving complaints and the products not, and they have evidence from other companies (Honey Stinger) who had similar issues.
I wonder if they run any sort of A/B testing. Wouldn't harm if they sent few packages with one ingredient missing once in a while, then see what's the response.

The idea of using A/B testing for food safety testing is horrifying.
