No they don't. From your link:

> The first draft of the paper, released last month, said the median profit was $3.37 an hour, but the author released a new analysis on Monday following criticism from Uber. In the new analysis, the researcher reported the higher median profit of $8.55 an hour.

Another quote from your link:

> Alex Tabarrok, a George Mason University professor who called the paper’s findings “dubious” last week, said he still had concerns about the researcher’s reliance on questionable survey data and that he believed the average hourly profit of Uber drivers was closer to $13 an hour (similar to figures the company has cited).
