Key legal question
Whether the mixed-method allocation of 70% gainful activity and 30% household activity was reviewable as erroneous fact-finding.
Extracted holding
The allocation was based on evidentiary assessment, was not manifestly incorrect, and remained binding on the Federal Supreme Court.
Extracted reasoning
The determination of the hypothetical activity split is a factual question when it rests on appreciation of evidence; the appellant’s criticism was inadmissible appellate argumentation.
