The measurements of inclusive electron scattering from nuclear targets carried out at the Thomas Jefferson National Accelerator Facility in the mid 2000s have provided valuable novel information on the $A$-dependence of the modifications of nuclear structure functions known as EMC effect.We argue that these data are best described in terms of the scaling variable $\widetilde{ y}$, designed to take into account dynamical effects in interacting many-particle systems, and analyse the $A$-dependence of the slope of the inclusive cross section ratios, $R_A = (\sigma_A/A)/(\sigma_2/2)$, providing a measure of the size of the EMC effect in the region where nuclear binding plays a leading role. The results of our study reveal a linear correlation between $dR_A(\widetilde{ y})/d\widetilde{ y}$ and the average nucleon removal energy $\langle E_A \rangle$. The role of correlation effects in the determination of $\langle E_A \rangle$ is highlighted.
