May be best not to wonder, but how do the ticket ballots actually work. Is there a giant sack containing a ball with each of the applicants' supporter numbers on and Liz Finney takes them out one by one and someone else reads out the names up to the limit of tickets and writes them down on a piece of lined A4. Not sure how that would work with 1s, 2s and 4s but possibly there is a state of the art random number lottery generator or something.
