Operator reliability index
How reliably each charging network publishes live status to drivers. Scores use live-status share, feed uptime and a stale-status penalty — never the feed name.

How the score is calculated
For each operator with a live-capable feed, the daily score is
clamp(0, 100, round(100 × (0.50 × live_share + 0.40 × feed_uptime + 0.10 × (1 − stale_share))))
- Live status share — share of charge points with a fresh status (available, in use or out of service, reported within the freshness window), as on the statistics page. Stale reports do not count.
- Feed uptime — over the last 30 days, the share of finished scheduled sync runs that succeeded for the feeds that carry this operator’s stations. We never name the feed.
- Not-stale share — one minus the share of charge points whose status is older than the freshness window.
- Every operator with a live feed is rated, however small: the figures count all of its charge points, not a sample. Operators with only static register data and no live feed are shown as not rated on their data-quality page and omitted from this ranking.
