I've always been a bit confused about Cracklib, but have a look at the module in PAM's manual.  Maybe that can help clear things
up.  Read the part about minlen, it appears you get credit for more
letters if your password is very different from the previous one, etc.

I'm not the expert here, William.  In fact, until a week ago, I don't
think I understood this process.

Hope that helps.
