Number of conductance parameters that were constrained sufficiently given a particular model and simulated protocol. Our definition of success is that M < 0.05 for a parameter for the length of the MCMC chain (having removed the first quarter as a burn-in period). ‘n/a’ stands for ‘not applicable’, and indicates that the models do not include the components necessary to perform these protocols. N.B. Gto1 appears in [9], but Gto is in all other models in which the current is modelled.
