I am sorry Gkyr, dont look at the math under the spoiler if it causes you pain. I am pretending I never saw the math under the spoiler! I love my GA
Edit: for clarity.
Although GA may increase tournament/spire difficulty more than residences do (for the same amount of population), arguments can still be made in favor of GA. For example, to take advantage of the higher efficiency of residences, a player has to be able to place lots of expansions to build residences on. However, placing more expansions may not always be possible because the player has used up all available expansions or because the price of premium expansions has become prohibitively expensive.
In other words, the argument in favor of residences assumes that the number of expansions one can place is unlimited. That may not necessarily be the case, and GA may come in handy under some constraint on the number of expansions.
I know that the effect of expansions on tournament/spire difficulty has already been included in
@Jikuyin's calculation, and the point I am making is a different issue.

@Iyapo1: I know that you have invested heavily in your GA, and just wanted to say that the investment may still be worth it. If many people agree that GA is really good, I believe there would be some truth to that. If the calculation says otherwise, then the calculation might be missing something important.
