## How this was measured

One price per station per day. The daily history table holds one row per station, fuel and day. A row is also written back to the date the source itself gives as the moment of the change, so a change lands on the day the operator made it, not on the day we happened to read it.
A change is two consecutive days in a station’s series with different prices; it is counted on the second of the two. If more than 3 days separate the two readings, the pair is dropped — there is no way to say which day the price moved.
A market-wide move — a “wave” — is a run of days on which at least 50% of the stations with a price changed it; the threshold is not a fixed number but the market’s own median plus half the way to its 95th percentile. Within a wave each network gets the centre of gravity of its own changes; the network whose centre falls earliest moved first. Waves found in this window: 8.
The figures are rebuilt once a night from the full history, not on every visit.

## What this cannot tell you

At most one change per station per day is visible, because the history keeps one price per station per day. A station that changes twice in one day is counted once.
It cannot be established for Spain. Our history keeps one price per station per day, so we know the day a price changed but not the hour. Nothing on this page claims otherwise.
