is there any correlation between number of fans and spectator who come to the stadium?

if i have 200 fans and my stadium capacity is 300, is it possible to get 300 spectators (full capacity) at home match?

and if i have 300 fans and stadium capacity is 200, do i need to increase my stadium capacity?



and i think 10 money from 100 spectators is not really significant revenue

It was said once that its good to have same size stadium as your fans.

With that said - there are many factors about stadium.

Number of people at the home game = your fans + opposing team fans + random spectators.
Higher you are in the tournament - more people will come to see your game = higher revenue.

Ex.:
I have 1,000 people stadium but only have 600 fans.
In the final I play somebody who had 1500 fans.
My stadium will cap out at 1000 fans = 100 game money.
If I had a stadium of 2500 seats, I would probably filled it in that game.
Here is how:
600 of my fans + 1500 of opponents fans + 400(more or less) random spectators = ~2500 people watching (250 in-game money)

Hope I explained it well
