Outside the measurable population
Legacy News Topics: Top lists in the Machine Relations Index
Not measurable in this benchmark. The Legacy News Topics node only receives news-shaped prompts, so the Top lists pairing accumulates no observations and is excluded from the measurable population and from every published rate. This is a property of the prompt basket, not a finding about the market.
Segment-specific denominator. Not the overall domain denominator.
Release floor: 7 dates.
Only released domains with evidence in this exact segment.
Observed domains
No observations, and none expected
This pairing is never sampled, so the absence of rows is a property of the prompt basket and carries no information about the sources in this market.
