Right, this is where I think he is being misleading, because his equation doesn't allow for an entropy variable. You are right in that is how he is using it, but I don't think he is being accurate via the assumptions he has made.
Just to be clear, I would use this tool to provide guidelines. It's a reasonable representation for various scenarios or character set, and length, but I'm not sure it's really striving for complete accuracy in every situation. -- Roger A.
