There's a pretty easy way to tell how many penalties there were - all the matches are on
http://www.more.net/content/2012-qualification-matches. It looks like the 72-0 match had 9 foul points.
I noticed a side effect yesterday of not announcing what fouls are for - 60+ matches in and teams are still getting fouls for things like handling the balls during autonomous. That shouldn't be happening 60+ matches into a regional.
