For each of the three elements - teacher, class and subject - you can define a factor that is multiplied with the value of a lesson. You can also display the subject and class factors in the lessons window.
Please open the Demo2.gpn file and in the “Lessons | Teachers” select teacher “Arist“. Look at lesson number 79.
The lesson has 5.470 value units and is calculated as follows:
Weekly periods (5) * Teacher factor (1.000) * Class factor (1.105) * Subject factor(0.990) = 5.470. All factors in the master data are included in the calculation.

If these factors are not to be taken into consideration, check the corresponding boxes on the “Value Calculation” tab under “Settings | Miscellaneous” and the value for this lesson changes to 5 (the number of weekly periods).
