It's 10% of capacity up to a ceiling of 3,000.
As for our attendances, we need a bigger ground but our slightly bonkers owner has fallen out with the owner of the stadium and it's stopped any expansion, at least for now(our average attendance is only 800 below actual capacity and that's mainly down to away fans not taking their full allocation). We took over 40,000 to Wembley for the play-off final, there's plenty of City fans that would love to be at Wembley but won't get a ticket, it's not just you lot.
