Why this scored 6

every term, weighted
Velocity+0.0 / 40 max

Engagement per hour, normalized against the fastest item on its own source

Acceleration+0.0 / 25 max

Whether that velocity is itself speeding up, as a per-hour rate

Cross-source spread+0.0 / 25 max

How many independent communities are talking about the same entity

Recency+8.6 / 10 max

Decays to zero over 14 days

Saturation penalty2.1 / 30 max

Subtracted once something is big and old — we rank what's next, not what's peaked

Composite6.5

Weights are hand-tuned, not learned — we're calibrating them against realized trends as history accumulates. On a topic's first sighting there's no previous reading to compare against, so acceleration starts from a neutral prior rather than a measurement. Full methodology
