Questão jurídica principal
How should the insured person's valid income be determined for invalidity comparison?
Decisão extraída
The valid income could not be based on the temporary hourly wage extrapolated to a full annual salary; tabular wages were the proper basis.
Fundamentação extraída
The insured had a history of temporary work with varying wages and incomes well below the cantonal figure. Extrapolating the last temporary hourly wage to a full-time annual income was not realistic; using LSE tables better reflected probable earnings.
