I've tried to understand how video views and eCPM works. For example on one video on YouTube I had 6,605 views and an eCPM of $0,46. Is it correct if I calculate it this way: 6,605 x $0,46 = $3,0383? The earnings in the last collumn on my 'stats and analytics' says: $3,02. So there is a difference of almost 0,02 cent. The higher the views the more difference there is, although it is not much. Is this the way to calculate it? if yes, what is the reason that there is a small difference?
