Guild Rewards

Anyone know how they're calculated?
This references the Guild section in the ranks.

Here's what I believe to be true.

It says every Sunday that the points and rewards will be calculated. I believe the rewards are just resource points.
The ranking is determined by the column titled "Accu. Points". Every time we win in guild wars we get 3 points, the loser gets 1. I also think if there are an odd number of guilds and you get paired up with no one you get 2 points and a by-day.

Eventually everyone but us will lose in guild wars, solidifying our place on top for life.

Of course, I could be wrong. Time will only tell what's true.
