  For Szilard's engine and Landauer's principle, it is largely agreed that numerical evaluations allow us to set SBi = SGi = S′Gi for all macrostates, by the adjustment of a single additive constant (this is equivalent to saying that entropy differences between macrostates are the same for each definition of entropy). Where there is no uncertainty over the macroscopic state, it can also be assumed SB = SP = SG = S′G. This has allowed a large amount of discussion to take place in the literature referring to ‘entropy’, without specifying which entropy is meant. Although this practice can cause confusion, it avoids unnecessarily cumbersome language in situations where the different entropies are in agreement.  However, when an argument is only valid for a particular entropy, or when these entropies disagree, it should be clearly stated which entropy is involved.
