Key legal question
Whether the cantonal court correctly fixed the valid income by averaging the hypothetical earnings of a gymnasium teacher and a journalist.
Extracted holding
The method was acceptable despite some factual inaccuracies, because the insured person's future career path was uncertain and the court even resolved the uncertainty in her favour.
Extracted reasoning
No concrete indications existed for a definite career path or for an increase based on experience. Using basic salaries from both plausible professions was not arbitrary.
