Kernrechtsfrage
Whether the residual earning capacity had to be calculated on a 4-hour workday rather than a 50% capacity against the average weekly workload.
Extrahierter Entscheid
The cantonal court's approach was not manifestly inaccurate; using a 50% reduction on the standard weekly workload was acceptable.
Extrahierte Begründung
The MEDAS report described the capacity as reduced by 50% and suitable work as 4-5 hours per day; the small difference from a 4-hour day did not make the calculation untenable.
