Wait, the user might not know specifics about HSB133. So I should make sure the explanation is clear even if it's hypothetical. Maybe mention if it's a fictional model, but for the sake of the example, present it as a real one. Alternatively, if it's a known term, reference that. Since I can't verify, proceed with a general approach.
