\subsection{Benchmarking ProCS against full QM calculations}  Eq (1) \ref{eqn:procs}  is parameterized using OPBE/6-31G(d,p)//PM6-D3H+ calculations so we compare ProCS15 against full OPBE/6-31G(d,p)//PM6-D3H+ calculations on ubiquitin (1UBQ) and GB3 (2OED) to test for errors introduced by the inherent additivity assumptions and the structural simplifications in the model systems used for the DFT calculations. The results are summarized in Table \ref{table:vsqm}. The first row, marked "all", summarize results for ProCS15 if all but the last two terms of Eq \ref{eqn:procs} are included. The last two terms correct for the use of PM6-D3H+ as the structural model and explicit solvent effects, respectively and are thus not relevant when comparing to DFT calculations using PM6-D3H+ optimized geometries.
