Limitations
- An estimated outlook, not a validated forecast of station prices.
- Too few completed comparable periods for a historical-outcome signal; the view uses observed trends and current context.
- Live AI research is delayed; previously sourced incidents keep their original dates and lose weight with age.
- Local pump publication time is unknown. Collection history is useful context, not proof of when stations repriced.
How to read this forecast
- Price pressure
- A heuristic score from −100 (downward) to +100 (upward). ±12 or more reads as directional pressure. It is not a percentage price change.
- Fill-up timing
- Whether buying sooner, waiting or no rush is likely to make a difference. It is withdrawn when the latest report is delayed.
- Confidence
- How much fresh evidence supports the outlook. Low confidence means the signals are thin or mixed.
