I am well aware of the fluctuations of the fan survey. It (the survey) doesn't mean anything. It is simply a very vague barometer of how many people will show at your next home game and how much merchandise you will hock. Putting stock in it at all is silly. It says on the fan survey page that it is possibly inaccurate. Why would you take it seriously when it says that?
Like I said in the post you replied to, don't take any of it too seriously.
Once I scored a basket that still makes me laugh.
