An incorrect precise number is worse than no number at all: if you assure user that it takes 129,052,722,140 iterations to guess password "password", or 2,322,220,814,264,750,000 to guess "qwerty123456", it only misleads. The real attackers start guessing not from "a", but in the most-probable-first order. What is this order depends on the traits of the mark: the first password to try, can as well be "password", "qwerty123456", or "salasana". -- Regards, ASK
