The passage around this formula
…on unverified vendor numbers stacked several layers deep; a single shunt measurement campaign, even a short one, converts most of that stack into fact. Here is the fraction of time the device spends in power state i (sleep, always-on monitoring, escalated inference, radio) and is the measured — not datasheet-typical — power draw in that state. This formulation is worth writing out because it exposes the one lever that dominates every other design decision: since is normally close to one…
