I am not sure how to answer that question. I know that no optimization was done to it during its build and that some of the pages aren't coded the same when I do a Dreamweaver / view source.
If its all front-end code you see in Dreamweaver, you'll probably end up cleaning that when you do a next major redesign, you shouldn't waste time on it that you could be using to enhance your product in other ways.
Thanks,
