Password Strength - again

In an earlier post I looked at the XKCD cartoon that proposed a different method for creating a secure password than much of the industry suggested material. I came across this site - - where you can check the strength of passwords you're using. 

So I tried the two passwords in the XKCD cartoon and "Tr0ub4dor&3" came up with this result:
Length: 11
Strength: Reasonable - This password is fairly secure cryptographically and skilled hackers may need some good computing power to crack it. (Depends greatly on implementation!)
Entropy: 51.8 bits
Charset Size: 72 characters
and "correct horse battery staple" resulted in this:
Length: 28
Strength: Strong - This password is typically good enough to safely guard sensitive information like financial records.
Entropy: 104.2 bits
Charset Size: 27 characters
So it's kind of confusing isn't it. Of course, you shouldn't now use either of these passwords.

MV Torr Head

I did two trips from Ireland across the Atlantic on this ship in 1969. We sailed through the St Laurence Seaway and the Welland Canal as far as Chicago with stops in Detroit, Cleveland, Toronto, Quebec and Montreal. She predated containerisation but had been fitted to carry some containers as well as general cargo. We seemed to carry mainly whisky and whiskey to North America and beans on the way home. I'm sure she's long gone.

I only mention this because I found this picture on the net.

So if this is a good way to choose passwords, why does my bank, service provider and so in insist on me using M1xedC@53 passwords with special characters?

Thanks to xkcd for this.
