We intended that the passwords be roughly asymptotic in difficulty--so that many would crack fairly quickly at first, but they would get harder and harder (and thus crack slower) the more progress a team made. This seems to have pretty much worked as designed.

Here is a graph of all teams' crack performance over the life of the contest. Note that many teams did not start right away, some as much as halfway through the competition. (Yes, we ran out of good contrasting colors.)


Each team's cracks over time are graphed below. Where we have a writeup from that team, their graph is a link to it.
