When several teacher share a coupled lesson, the value for each coupling line is calculated as for one teacher , and these values are then added together.
Caution: Class not in coupling line
If the class in question is not in a coupling line, the value of the coupling line will be 0.
Example: Value of lesson 77 for class 1a

| • | First coupling line, teacher ? |
Two weekly periods for a class, the value is 2.000.
2 / 1 = 2
| • | Second coupling line, teacher Gauss |
Class 1a is is not included in this coupling line, the value is 0.000.
| • | Third coupling line, teacher Curie |
Two weekly periods for two classes, the value is 1.000.
2 / 2 = 1
| • | Total value for lesson 77 |
The total value for the lesson is the sum of the coupling lines, i.e. 3.000.
2 + 0 + 1 = 3
