My tests were informal. The target was mostly taken from the sci.crypt readership -- I don't deal much with management...
The initial tests were on passphrases of lengths from 12 to 20, as I recall. The phrases were created by chosing random words from /usr/dict/words -- and the resulting pass-phrases were exceedingly weird, which may have contributed to folks difficulty in typing them. Not that the scores were bad, but they weren't great.
I wonder how much the success that I (and apparently others) have with long pass phrases is due to the fact that we pick our own sentences which have some meaning (presumably) to us. josh
