Not measurable in this benchmark. The Legacy News Topics node only receives news-shaped prompts, so the Is it worth it pairing is never sampled, accumulates no observations, and is excluded from the measurable segment population and from every published rate. Its emptiness is a property of the prompt basket and says nothing about the sources in this market.
