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.
