Uber's complaint was that he assumed that when the questionnaire asked about the hours per week people worked across all on-demand services, their answer only included the hours they worked driving for companies like Uber, but that for the next question about money earned across all on-demand services their answer was their total income and should be multiplied by the percentage of their total income that came from driving given in a later question to get their Uber income. Those assumptions are basically incompatible with each other.
