I started updating the stadium page at https://top-eleven.fandom.com/wiki/Stadium

Anyone who's in different levels can help to updated the pending values marked in italic:

- Stadiums build time, seat capacity, costs and rushing costs;
- Included upgrades sizes, costs and rushing costs, need data for all stadiums level (except 0 and 9);
- Included the attendance cap (seems ok);
- Included rewards but need info on the frequency of rewards at medical and training buildings, and cars capacity of Ultimate Garage.

If not a fandom user, just post here any of those info you might have.
