Rows on the live instance were mostly bursts of a few minutes: 28 of 52 peaked within the metric's own usual peak, and 42 of 52 latest occurrences lasted 30 minutes or less, which is what a burst shorter than the 15-minute average looks like once its span is back-dated. Nothing asked how high or how long, as the System 182 ruling says a normal records. A departure now also has to be past the slot's usual peak, or held: the median of the last hour over the same line. Those spans were also keeping the burstiest hours out of learning, lowering the usual lines further. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
