28 NEEA & PG&E s Supplemental Test Concept: Combine D2 test results with additional tests runs using real clothing in multiple operational modes. Benefit Increased accuracy of relative ranking Correlation to field results Eliminates optimization for just one test condition with non-realistic clothing type 28
