* wird student 30 Tage gutgeschrieben, aber teaching sinkt auf 0 (300-11x30 <=
* 0).
*
* Sonst traete dies auf:
*
* A: lernt B: lehrt A C: lehrt A D D: lernt
*
* Wenn B vor C dran ist, lehrt C nur 30 Tage an A (wie oben) und
* 270 Tage an D.
*
* Ist C aber vor B dran, lehrt C 300 tage an A, und 0 tage an D,
* und B lehrt auch 0 tage an A.
* (Na und? -stm)

* Deswegen darf C D nie lehren duerfen. (Warum? -stm)
