We can perhaps learn a bit more from these non-ranked submissions by comparing to the ranked submission called FS-DAM/GAFF2/OPC3, which uses the OPC3 classical 3-point rigid water model with the GAFF2 force field and performed better than methods using its TIP3P counter part with GAFF, though there were other methodological differences between these submissions. The prediction error values for this method were the closest to the top performing methods using free energy methods with the AMOEBA force field, however its correlation values were similar to the methods using GAFF/TIP3P. The OPC3 water model has been shown to be significantly more accurate for pure water properties compared to other popular 3-point water models (i.e TIP3P and SPCE) of the same class which may be particularly important in this system. Given the results reported in ref for OPC3 and ref for GAFF2; it is tempting to attribute this method's better performance to use of the OPC3 water model and GAFF2, though without comparison to other methods which differ by only small molecule force field or water model, it is difficult to know this for certain.
