LXF 182, p80, passwords, it was stated that the password "Ff%#ht!4-2" has an entropy of 27 bits. How did you come to this number? It seems that you have used the full printable ascii character set, which equals about 6.5 bit entropy per character, hence above password would be 65bit entropy? What do I miss?
Anyway, it is very unclear how you came to all the entropy calculations
(I tried to read your reference 1.usa.gov/q3y5u, but it was a bit over the top for a relaxing saturday afternoon )
