Need clarification on survey scorecard calculation


How to calculate the scorecard and how does it works
What formula does it use for displaying the results?
How are the current and different sections calculated?


We are calculating the scorecard result specific to the assessment group. e: g list of category result and metric result with specific to the assessment group.
For example the metric "XYZ" . If you see total 6 metric results are there. However, only two of them are having valid assessment group. So the formula calculates on the basis of
(sum of normalized value/total number of assessment group *100)/100 . ((1.67+1.67)/2 *100)/100 which is 1.67 in the year 2019. Records without the assessment group are not taking into consideration.
