The cumulative retrieval success rate over the selected window for this provider and probe location, shown with its 95% confidence interval (CI). Each point is the running rate across every retrieval check up to that day; the shaded band is the Wilson score interval for that rate.
The band starts wide and narrows as checks accumulate. Once it sits entirely above (or below) the 97% approval threshold (the dashed line), the provider is statistically distinguishable from the threshold — which can happen well before any fixed sample target is reached. The dashed line on the right axis tracks the cumulative number of checks the rate is based on.
