And whether the adversary's goal is to crack:
A. Just one password for any account 
B. The password for one specific account
C. One password out of a specific group (say admins)
D. As many as practical. E.g., for resale or for a customer pentest report.
E. All passwords. E.g., password researchers or enthusiasts with bored GPUs :-)
