I don't know if anyone's mentioned this already, but I suspect the new electronic ticket readers that have been installed on the turnstiles at Ewood could herald a marked difference in the "official" attendance on matchdays.
I've often noticed in the past three or four seasons that the attendance figure announced during the second half doesn't seem to be as great as the number of seats that are filled with supporters.
And, before any wag starts asking me if I personally do a half-time head count, it's fairly obvious on occasion that there are several thousand more people in the ground than is claimed. You only have to look at the empty (or otherwise) blocks of seating.
I'll leave it to people's imagination as to why this discrepancy might occur, but I wouldn't be surprised if our average attendance figures were up a little this season.
