Next Community Prize: 20 Billion Goo

I don't understand the post about 20 million being a "big jump" to the next prize. Prize #1 = 5 billion, Prize #2 = 10 billion, Prize #3 = 13 billion, Prize #4 = 20 billion. Did the forget that from #2 to #3 it was only 3 billion. Also, I saw a picture of a hacked device that had all the prizes and the community meter was maxed out at 25 billion. That picture was a week or so and I'm sure EA can change the end total whenever they want.
