Maybe he didn't know the information you were looking for offhand? Or maybe it's rather complex and detailed?

To be fair, he answered your question. He confirmed there is no way to get it w/o sign-up, but acknowledged there should be and commited to provide it. Edit: Looks like the question was unclear to him, it's been provided below ;-)
