No, as you see in the last 3 logs the values didn't change much (save from color bonus, which changed the gross income a little), that is because I didn't make any changes in my nation. I'm also not the only one whose gross income and gross expenses look off, I asked for some people to send me their revenue and they are off as well. I couldn't find out what was wrong with the gross expenses calculation, but the gross income was (0.0135 * Commerce + 0.81456)*Population instead of the (0.0145 * Commerce + 0.725)*Population that it should be according to the revenue page and wiki.
