Tiger Shark, something like Johns -i:all, which I think is 95 characters. The formula is pretty easy if you know the approximate number of password tried per second:

((Number-of-characters-in-keyspace)^(Length-of-largest-key-tried))/(Approximate-number-of-password-tried-per second)=(how-long-it-takes-in-secs)

I'll take a look at the sheet.

/edit:Again, whole keyspace, all possible passwords are tried as if only the last one is correct.
