Nexus metric
Nexus Velocity™
Acceleration against the subject's own baseline — not absolute size.
What it measures
Nexus Velocity expresses how fast a subject's signal volume is growing relative to its own history, as a multiplier. 2.0× means twice the subject's normal signal rate; 1.0× means business as usual. Because it is self-referential, a small subject accelerating hard outranks a large subject coasting.
Absolute counts favor incumbents — big subjects always have more posts, stars and coverage. Velocity is the size-blind lens that surfaces the next thing while it is still small.
How it's computed
Signal rate in the recent window divided by the trailing baseline rate for the same subject, with a floor to avoid divide-by-zero on new entities. Displayed as a rounded multiplier; inside Nexus Signal it enters log-scaled at 20% weight — the heaviest single factor.
Signals per day across all ecosystems in the recent window.
Every qualifying signal counts once, regardless of ecosystem.
The subject's own normal, from the prior period.
Signals per day in the trailing window preceding the recent one.
How to read it
3.0×+
Surging
Exceptional acceleration — usually accompanies an event: a launch, a paper, a viral thread.
1.5–3.0×
Accelerating
Clearly above its own baseline. The classic early-breakout profile.
0.8–1.5×
Steady
Moving at its normal rate.
< 0.8×
Cooling
Below its own baseline — attention receding.
Velocity is noisy for very new subjects with tiny baselines; Nexus Confidence discounts exactly that case. Read a huge multiplier on thin evidence as a prompt to look, not a conclusion.
