From the intro post to this season of GTC :
‘The idea in every round is to guess what you think the official attendance figure will be, for that match. I post the figure that AVFC releases to the press at the end of every round on the Guess thread and award points according to how close you are to the total.’
I usually use the BBC sport report. If there’s a press outlet saying something different and it’s from AVFC, please let me know.
