In P197 (susceptible, left column) the 2 conformations are centered at scores 34.5 and 42.3. In S197 (resistant, right column) the conformations don't appear as well-defined and have center scores of 34.4 and 40.3; the less shaped peak is explained in the following. The score shifts and the population fraction in each does quantify the change of the interaction with the herbicide CS, in addition to peak shape (narrow, wide) and relative height.
