I've found it's not just the words in the dictionary. Given a fixed
length of time, anyone can make a list with more words than they could
check. It's the order of the words in the dictionary - getting the most
likely ones in there first. This is especially true when you're doing
authentication attacks such as privilege escalation or openrowset in SQL
injection, and you're only going to get to try 1-5 passwords per second.
Comprehensive is great, well-ordered is critical.
