LOL... I read that from the linkback on Bondo's thread. Of course, I instantly knew your handle.

Unfortunately, While I'd love to help you, I'm not going to, for the sole sake of not starting a "fight" between forums. If I had even the slightest thought that the people in that thread were interested in anything other than supporting their ego's, I'd sign up and post references.

You should know that a tonneau cover is not universally better. There are cases where it does nothing, usually with shortbed trucks (like some quad cad micros with 4 foot beds) because the flow detachment from the roof line never really reaches the tailgate to begin with.

You should also note that the flow simulators don't show real world conditions, they simulate a static shape in static wind conditions at a static speed.

Those things should not be the basis for your argument, rather points to consider when doing more research to figure out what you should be saying next.
