This paper is part of our broader investigation into the utility of discourse structure for performance analysis. In our previous work, we showed that several interaction parameters that use discourse structure predict our performance metric. Here, we take a step forward and show that these correlations are not only a surface relationship. We show that redesigning the system in light of an interpretation of a correlation has a positive impact.
