Before revision:  Through a careful analysis of each component of QAEval, we identify the performance bottlenecks and estimate that with human-level performance , QAEval's summary-level results have the potential to approach that of the  Pyramid Method.
After revision:  Through a careful analysis of each component of QAEval, we identify the performance bottlenecks and estimate that its potential upper-bound performance surpasses all other automatic metrics, approaching that of the Pyramid Method.
