OK Mr Bayeslisk, I am one boxing you. I am upvoting this post now knowing that you predicted I would upvote it and intended all along to include or add some links to the above post so I don't have to do a lot of extra work to figure out what RAND is and what book you are talking about.
If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
