If you fire your level 7 PR manager 20 minutes before the game, will the attendance drop? I suspect that the responses in the Fan survey will not change prior to the game after the firing.
Yes, firing your Level 7 PR guy 20 minutes will affect the attendance to some degree. As for the Fan Survey? I think you are right in that the Fan Survey responses will not change after firing your PR guy and before the game. However, the firing of PR guy will have some effect on the attendance which in turn will, I would presume, have some effect on the fan survey after that game.
As for how much and the certainty of this...
