I did a calculation for the attendance.
Arena 19000 you can max out.
After that the next 2000 will get max 1/2 attendance = 21000 can have max 20000 attendance (with 1-2 odd random attendees).
After that it's 1/5 attendance, for example: 26000 can have max 21000 attendance (with a few odd ones here and there).
Eventually you will gain from any attendee, just the time your investment pays back is long.
