Both landscapes have dimer corrections with intermolecular nearest atom-atom distances out to approximately 9.5 Å, and so the resolution of weakly interacting dimers is expected to be much lower than those with small intermolecular distances. However, given the relatively small data sets, and as these terms are expected to only make minor contributions to the energy, focus was given to accurately resolving strongly interacting dimers without significantly increasing the size of the descriptor space.
