Quality rule grade calculation

We can calculate the grade of a particular quality rule using below details:

Please note that QR grade depends on both failed check as well as total check.

Formula to calculate the grade:

(Total check- Failed check/ Total check) *100

For example:

In above screenshot you can see that for a QR, total check is 1559 and failed check if 15. As per the formula,

(1559-15/1559)*100

==99.037 =99.04

In screenshot we can see 99.04 is equal to grade 2.08
