ArchSetuAlert Threshold Calculator
Baseline mean, standard deviation, and a sigma multiplier - to an alert threshold that scales with the metric's own variance, plus the expected false-positive rate.

Alert threshold
~0.13%
Expected false-positive rate
Threshold = mean + (σ multiplier × std deviation) - scales with the metric's own normal variance instead of a round number that ages badly as the baseline drifts.
