Do you have an example for P087712 rating? In a very simple scenario with the entire competencies rate to 3 (in a scale 1 to 4) the total appraisal is 4 (why?) and also the group competencies are level at 4 (why?)

Could you help me with the origin of these calculations? Do you have an example for a real environment

We have an issue with the appraisal level calculation P087712. We have a very simple scenario where the calculations are not correct. In this example all the competencies are level at level 3 but the result in the superior level is 4 ¿?  And also the total appraisal is 4 when all the components are 3 ¿?
