Ad Networks will often change numbers after the initial posting of data: known as re-posting reporting. While this can sometimes be good– your earnings increase after initial posting– it can also be negatively adjusted as well. Regardless it always caused revenue reconciliation issues with accounting when the recorded reporting doesn’t match the revenue paid to the publisher at the end of the month. To keep as up-to-date as possible we continually back-fetch data to keep as-accurate-as-possible reporting with the network’s latest posting. For this reason, we don’t recommend you rely on earnings until 15 days after the initial posting.
