Having established the XSAPT formalism, we next discuss its inherent EDA scheme, focusing first on the accuracy of the energy components (Section 1.3.1). Then, we describe how the SAPT induction energy can be separated into polarization and CT contributions (Section 1.3.2). Finally, we discuss how many-body effects manifest in the EDA for systems with more than two monomers (Section 1.3.3).
