Random #

Regarding the coin reward for playing games in CC. Does EA just randomly pick a number and make the the reward. It fluctuates so much, even though the opposing AI team is rated matched. One game is 358 then next its 412, then 380, etc. Why. In games of old, it depended on the teams rating as an opponent. But now, like i said. Teams are pretty well matched. And its not goal differential. Had games that were lopsided, and ones closer. Still the fluctuation in coins. Is there a basis for the dispersal?
