First, that's still beside the point. You shouldn't evaluate a password scheme solely by entropy if it is a password you intend to memorize. XKCD argues that it's easier to remember 4 random words than 8 random characters.
Second, your example isn't very good because it assumes that every 8 byte character (save one) is acceptable, which is rarely the case, especially if you are trying to memorize them.
Finally, as another commenter pointed out, you've got your math wrong, and even your example has more entropy for the words than the characters.
