The acceptable Repair percentage is specified in the Client specification.
From your Excel sheet as below.
From your attached sheet, the Repair percentage is calculated in 2 ways.
1. Joint wise (no of Joints Repair / Total no of Joints RT shoot x 100).
2. RT Film wise ( no of Films Repair / Total no of Films shoot x 100).
From the Client specification, you can understand what is the 5% limit.
Thanks & Regards
