Information about the Batch Clusters
Craig-Paardekooper also discovered that the toxicity of the batches clusters alphanumerically into specific ranges of toxicity. And these ranges decrease linearly as one ascends the alphabet. So, besides using the batch search engine available on his site, victims can also get an idea of toxicity by looking at the batch code, and seeing if it falls into one of the above alphabetic series. Lower in the alphabet is indicative of higher severity, and higher indicative of lesser severity.
It looks like batches with different toxicity were carefully labeled and tested on the public, resulting in different side effects.
