I am asking this because i have noticed right now i played a home game and my capicity was 19k out of 19k (ticket price set at 7) however when the match finishes it comes up as ticket income 19k

So do ticket prices actually do or mean anything?

Also with stadium does it only increase with each level you are?.

For example i am level 5 and according yo my club section it says i have a capacity of 31k but when i play games its only out of 19k so does it just go up ever level instead of how much you build?
