Those numbers 100,000 and 115,000 look to me as some meaningless numbers. They do not have anything to do with reality. It has never been 100,000 and has never been 115,000Let's count. DV10 ~100,000 winners = 50000 visa, DV11 ~100,000 winners = 50000 visa, DV13 ~115,000 winners = 50000 visa.
Now count on the aspect ratio. I do not understand where the difference and do not respect? 2013 is different because of the additional mailings.
