Oh, very cool, thanks for posting. I had actually written a really basic cracker and started seeing if I could figure out how many of them belonged to shorter passwords, but you're doing a much, much better job of it than I am (I was just brute-force generating short passwords, no wordlists or anything).

Are you planning to make a blog post or anything "final" with the info you find out, or will you just keep updating those gists?
