This is true, in regards to the country your views take place in. Combine that with however many mobile views you're getting and these factors play a big part in how much you will earn from the views you gain. Also, as was mentioned before, at the beginning of a new quarter advertisers are still setting up budgets and a quick dip will take place in CPMs. This is the case in both networks and adsense through YouTube.
Well said Austin
