I am sure I am not the only person who goes to watch Norwich at Carrow Road who is completely confused by the attendance figures that are read out during the matches.
Against Southend on Boxing Day, there were 25,433 fans present, which according to the announcer was "an 86% turnout". This would mean that a 100% turnout would give the ground a capacity of 28,900 people. Yet against QPR on 30th December, there were 25,113 fans at the game, which was according to the announcer "a 90% turnout". This would make the ground capacity 27,600. So on 30th December Carrow Road had a capacity of 1,300 less than it did on Boxing Day ?
Having checked the facts, it appears that Carrow Road's official capacity is 26,034. This would make the attendance on Boxing Day 97%, not 86%.
These odd percentages are read out every week, each one just as bizarre as the next. Could someone explain how Norwich City come up with their percentages. As a teacher of maths, I cannot come up with any mathematical way to explain it.
