Confidence travels with the score
Evidence coverage matters.
STX Index™ turns multiple signals into one qualified view.
STX is not a raw audience number. It combines audience, growth, momentum, acceleration, consistency, competition and anomaly/event evidence, with confidence travelling alongside the score.
Seven weighted components.
| Component | Weight | Role |
|---|---|---|
| Audience | 30% | Measured audience scale |
| Growth | 20% | Comparable-period change |
| Momentum | 15% | Current direction |
| Acceleration | 10% | Change in movement rate |
| Consistency | 10% | Stability of observed performance |
| Competition | 10% | Relative market position |
| Anomaly / Event | 5% | Unusual observed movement |
Missing is not zero
Unavailable evidence is not silently treated as poor performance.
No invented causality
STX qualifies signals; it does not manufacture explanations unsupported by evidence.

How to read it
Three habits before you quote a score.
Read the confidence first
- A high score on thin evidence is tagged preliminary
- Confidence shows how much of the evidence exists
- Quote the two together
Compare like with like
- Same period, same group
- A score is relative to the comparison
- Say which comparison you used
Ask what moved
- Growth, momentum and acceleration show direction
- Consistency shows how steady it is
- Anomaly marks unusual movement, not a verdict
Questions, answered
Straight answers.
Is STX a raw audience number?
No. It combines audience, growth, momentum, acceleration, consistency, competition and anomaly evidence into one qualified view.
What if a part cannot be measured?
It is shown as unavailable and never silently counted as poor performance. Missing is not zero.
Does STX explain why a channel moved?
No. STX qualifies signals. It does not invent causes that the evidence does not support.
Where is STX shown?
On channel views, in rankings and on the live compare screen, always with its confidence and period.
