The statement "deriving accurate rankings.." is not supported by the previous sentence. Boltzmann weighting relies entirely on energy, so how is accurate ranking going to help improve "computational predictions"?
As the example in Figure 9 indicates, small deviations in relative energies and thus rankings can significantly affect the Boltzmann-weighted averages for properties such as dipole moment. This was the whole reason for including this section of the manuscript - several discussions of our preliminary work suggested such small differences were irrelevant. The work by Vo and Johnson, our colleagues at Pitt, give an indication of why accurate conformer rankings are needed.
In the revised manuscript, we have omitted the phrase "deriving accurate rankings" as it is redundant with the phrase "accurate relative energies" in the same sentence.
