For a fully-connected four-state model with all unit rates except for $R_{1,2}=expF$ and initial state $x=1$ (that is $p_0^{\mathcal{X}}(x)={\delta }_{1,x}$): (dashed) the effective affinity F; (continuous) estimator ${\widehat{F}}_{\text{fr}}$ of $log{\mathfrak{f}}_{+}/{\mathfrak{f}}_{-}$; (crossed) estimator ${\widehat{F}}_{\text{cy}}$ of $\text{sign}({\mathfrak{f}}_{+}-{\mathfrak{f}}_{-})log{\mathfrak{f}}_{\sigma }$; (bullets) the linear regime estimator ${\widehat{F}}_{\text{lr}}$; (triangles) the entropy production estimator ${\widehat{F}}_{\text{kl}}$. The ultimate stopping time was set to $N=20$ and the number of samples to $M=10,000$
