Last quarter people drew attention to the different accounting methods used for pool versus other uber services, with pool booking the entire price of the ride

Last quarter people drew attention to the different accounting methods used for pool versus other uber services, with pool booking the entire price of the ride as revenue rather than just uber's take. Does anyone have a sense of how much of the increase in revenue is due to increased ridership versus a shift in demand towards pool? Do flat fares use the same methodology?
