Agree that the fan survey and/or it's impact needs a slight rework.
Just to give a couple examples:
Last season, with a W-L of 12-2 at the time, lost an away game that was not a rival or TV game and had attendance drop from 375k to 325k from game before to game after that.
This season my first home rival or TV game won't be until 5 games left in the season with home game vs rival being the last game of the season, essentially doing jack all if I win or lose. On top of that both the first rival and TV games of the season were on the same week, while I also played a strong II division team in the cup game.
A few seasons back while having pretty much a perfect season in the league, had massive attendance drop after selling a bench player, and even more drop after selling another bench player.
Not sure what the changes should be like, just wanted to share my experience. :)
