What these numbers mean
0 cancelled and 0 unknown outcomes are excluded from the success percentage. Request success means the provider answered; it doesn't mean the code or task succeeded. The likely range is a 95% Wilson interval: with few outcomes it stays wide, and one bad day can move the rate a lot. Rates need at least 20 known outcomes and averages at least 5 timed reports.
