Kernrechtsfrage
Whether disability had to be assessed under the mixed method or the general income comparison method.
Extrahierter Entscheid
The mixed method was applicable because the cantonal findings that the insured person would have worked 67% and run the household 33% without impairment were not shown to be manifestly wrong.
Extrahierte Begründung
The assessment of the hypothetical workload is a factual finding binding on federal review unless manifestly incorrect. The cantonal court relied on concrete indications from the household report and the file; the social welfare situation did not establish that full-time employment would have been expected in the absence of disability.
