Kernrechtsfrage
Whether the invalid income had to be based on the last wage from the former or later short-term jobs rather than on LSE tables.
Extrahierter Entscheid
The lower court did not violate federal law by relying on the salary statistics for the services sector; the previous employments were too remote or too unstable to serve as the decisive benchmark.
Extrahierte Begründung
For the valid income, the decisive question is what the insured would probably have earned at the earliest possible pension start. Normally the last earned wage is used, but here the earlier job with Firma X. was six years before the relevant date and the later job with Firma T. lasted only briefly and ended well before the pension period. A continued equally paid employment was not established with predominant probability.
