edit*** Just to be clear I HAVE NOTHING TO DO WITH EXPOBRAWL*** Just tossing out some numbers
It does bring in a ton of cash, but there are some decent costs associated with any event like this.
$85 per team registration cost
minus $20 for 2 shirts
minus $5 for 'breakfast' doughnuts
minus $15 for 2 lunches
equals $45 actual cost to play per team
$45 X 56 teams = $2520 in the pot.
Then you need to take out for trophies. Last year trophies were pretty nice.
7 divisions with 4 trophies per division (2 for 1st and 2 for 2nd in each division) = 28 trophies X ~$40 per trophy = $1120
This leaves around $1400 not accounted for. That is pretty easily eaten up by even a small miscalculation from my above guesstimates.
Heck, I would guess from what I have heard that the expo organizer probably charges the expobrawl team just to use the room??? Just a WAG, but it would fit with the MO of what I saw last year.
Basically, I do not feel too bad paying $12.50 per person for all the effort that goes into running something like this even if it is just being pocketted. As far as I am concerned, I could do without the tshirt and lunch to save on cost per person (esp since my wife can't even eat any of the food). In the grand scheme of things, it is just pinball and it is worth the price since it is loads of fun!
