Well, I sure notice a difference. It may not be at 70 mph, but at higher speeds I can sure tell. I have driven them with all 3 options that you mention. None, regular placement, and moved back. The only difference that I have noticed is when it was on or off. It is not nearly as stable if it is off then when there is a spoiler. I have also heard that it is a functioning spoiler and would agree.
