I am quite happy with the attendance question, especially as I have gained quite a few 5 point hauls from it

.
I appreciate that the published rounded-up ticket sales do give an advantage to those doing their predictions later. However I have seen cases where even the club estimations have been a way out. For example on the Thursday the club were talking "almost 23k tickets sold", however the official website yesterday evening were saying "with around 25,000 fans expected to be in attendance". That is
potentially 2k of ticket sales for a game which went on general sale on 20th January. Is this some kind of ploy to further drive ticket sales? I admit that, prior to the news article I'd have guessed around the 21-22k mark, so yes I have been swayed.
Most league games are fairly easy to get a "ball park" figure well in advance. Take Sheffield Wednesday; I think it is safe to say around a 29k attendance is almost a given. While it wouldn't have been part of a prediction league, Morecambe on Tuesday night, they would have brought very few fans, and being an evening game, perhaps many families with younger children wouldn't attend along with people who have work commitments. Therefore an attendance guess of around 22k would be a reasonable estimation, I feel.
There are only 14 of us doing the prediction league, with the information at hand and allowing for ticket sales afterwards, there's still quite a large window of several hundred to work with.
