Kernrechtsfrage
Whether the invalidity degree had to be assessed by income comparison or the mixed method.
Extrahierter Entscheid
The mixed method did not apply; the insured would have worked full-time without impairment, so invalidity had to be determined by income comparison.
Extrahierte Begründung
The evidence showed a probable full-time work pattern in the absence of disability, despite prior part-time activities and family circumstances.
