These tables give worst case times only. Actual times will be a lot
lower - typically several orders of magnitude lower for human-chosen
passwords - because the probabilities of individual characters are not
equal and are not independent.
Also, attacking multiple target password hashes at once may result in
much shorter average time period between successful guesses. It depends
on the use of salts or lack thereof.
