Its job in the formula

$f_s$leep is a part of this expression. Its role is fixed by the surrounding article and by the operations shown in the formula.

Where the article explains it

This formulation is worth writing out because it exposes the one lever that dominates every other design decision: since $f_{\text{sleep}}$ is normally close to one and $P_{\text{sleep}}$ is normally the smallest term, the average power is overwhelmingly sensitive to the escalation rate — how often the cheap monitoring stage decides something interesting is happening — far more than to how efficient the expensive inference stage is once escalated.
