Decisione estratta
The 10% deduction was within the court's margin of discretion and did not violate federal law.
Motivazione estratta
The deduction must be assessed globally on all personal and occupational factors; the cantonal court properly considered age and long service, while the claimant's inability to continue heavy work did not automatically justify an additional deduction.
