The passage around this formula
Gavin Crooks sharpened this two years later into a statement about entire probability distributions rather than a single average. If is the distribution of work values measured over many repetitions of a forward protocol, and is the distribution measured over the time-reversed protocol run from its own correctly defined reverse-equilibrium starting ensemble, the two distributions are related by
