Asked about Running judges on live traffic
Your judge marks 80% of traffic as passing. Is the pass rate 80%?
An answer that works
Not exactly. The judge misses some failures and wrongly fails some passes. With its catch and accept rates measured on labelled data you can correct the estimate, and you should report the uncertainty that comes with those measurements.
