Why this scored 27

every term, weighted
Velocity+31.1 / 40

Its fastest-moving item, measured against the pace of its own source

Acceleration+0.1 / 25

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

Cross-source spread+0.0 / 25

How many independent communities its own items come from

Recency+0.0 / 10

Decays to zero over 14 days, counted from when we first saw it

Saturation penalty−4.1 / 30

Subtracted once something is big and old — sized by its biggest item, aged from when we first saw it

Composite27.1

Weights are hand-tuned, not learned — we're calibrating them against realized trends as history accumulates. On an entity's first sighting there's no previous reading to compare against, so acceleration starts from a neutral prior rather than a measurement, and velocity falls back to engagement over its whole lifetime until a second reading exists.
