Why this scored 10
every term, weightedVelocity+0.0 / 40 max
Its fastest-moving item, measured against the pace of its own source
Acceleration+0.9 / 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 its own items come from
Recency+9.7 / 10 max
Decays to zero over 14 days, counted from when we first saw it
Saturation penalty−0.5 / 30 max
Subtracted once something is big and old — sized by its biggest item, aged from when we first saw it
