If this criteria is optional and is for X points. Will it be excluded from the total score i.e. 100-X
Points for optional appraisals are not deducted from the denominator while calculating the percentile score. In case that an optional appraisal is not attempted, points will be deducted from the numerator while calculating the percentile score for the project.
For example if 100 points are applicable to the project and it chooses to not attempt or is denied 20 points across various criteria then the total score will be 80/100 i.e. 80%.
