Wouldn't even be just before kick-off either. They'd probably glance at the main stand ten minutes before kick-off - the weather was nice before the game started, so there were a fair few on the other side under the press box - make up a figure and then worry about what they're going to say in their preview; by the time they get on air, the figure is nonsense. I know we don't have the biggest crowds in the league, but that still doesn't excuse reporting nonsense.
