I like the idea behind the tool, somewhat, but I don't know how exact it can
be. I think Alexander's reasoning below has some strength behind it. Is it
something like trying to predict when a random number might come up. Keep
rolling an n-faced die for long enough and sometimes your number may come up
near the 'beginning' or near the 'end'. Who can say? Obviously, that all
depends on how the program is actually implemented to brute force. Is it
Which also makes me wonder, what is the 'seconds to crack' based on? A
single machine? An array of distributed machines etc?
I think you can give some 'good' idea of how strong the passphrase is but
maybe not as exact as you hope. I could be wrong(and often am).

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
