In the context of an immutable sequence with a uniform distribution, you can calculate the compound probability that a specific prefix repeats after a certain number of keys, and this does not require knowing how many times the prefix appears in the complete sequence. Instead, it is based on the theoretical probability under a uniform distribution. As I’ve said a thousand times before, my approach is not about predicting prefixes. It is solely based on skipping theoretically improbable ranges (temporarily, as I explained in the link I shared with you), using already found prefixes as a reference. It’s simply about probabilities—a statistical search strategy, nothing more.
