Thirty-nine “beginner” raters executed an Assessment of injury to the wall area, finishing sixty six ratings first with no DOFD approach and second, recurring rating Along with the new DOFD system. The effects indicated that the newbie raters had been extra trustworthy in their analysis of your DOFD to gypsum wallboard when using the DOFD approach. These success assistance the usage of standardized procedures to lower the variability in information collection and interpretation.
