Reference table
Flat metric: stability or ceiling saturation?
Six signals that tell genuine stability apart from ceiling saturation when a satisfaction or rating metric stays flat for quarters. Look at the distribution, the top-box share, variance across waves, the link to behaviour and whether known improvements registered. Use it before you call a tracker mature.
Where this appears
What's in this reference table
| Signal | Genuine stability | Ceiling saturation |
|---|---|---|
| Mean over time | Flat | Flat |
| Distribution shape | Spread, roughly stable | Spike at maximum, growing |
| Top-box share | Well under 15% | Above 15% and rising |
| Variance | Stable | Declining over waves |
| Correlation with behaviour | Consistent | Weakening |
| Effect of known-good improvements | Detectable | Undetectable |
