FTA: "One caveat: this analysis estimates advertiser demand for access to a given profile. It does not reflect the exact revenue Google receives from any individual user. What the model reveals is the ceiling, the maximum price the market places on your attention."

From this I believe that your problem can be solved. In accounting terms, the 1605USD isn't a flow (e.g., revenue) but rather a stock (e.g., receivable). They've estimated value about how much a profile is worth, which you shouldn't use to draw those conclusions about revenue.
