Kernrechtsfrage
Whether the cantonal court unlawfully set the table-wage deduction at 20% when calculating invalidity.
Extrahierter Entscheid
The 20% deduction was not a misuse of discretion; the cantonal court's assessment was sustainable.
Extrahierte Begründung
The question is a discretionary one reviewable only for legal error. Given the medical limitations in the adapted work profile, age and long service did not make the 20% deduction arbitrary.
