What the article says around this equation
where is the energy spent in one full wake-sense-infer-sleep cycle, the first two terms are housekeeping power integrated over the time spent in each state, and inferences each cost a measured . Every term in that expression should be a number taken off a current probe at the actual rail, not a value copied from a component’s datasheet, because sleep current in particular is notorious for being dominated not by the processor but by whichever peripheral, pull-up, or leakage path the design forgot to disable.
