Correct me if I'm wrong, but it looks like we have two means and methods with the same end result.

A: computer model (fluidynamic description) and 1/2 bed cover (aft half, right?).

B: scale mode and full bed cover.

Like I mentioned, older/earlier reports recorded a great increase in lift. I can only assume that there must have been some slight but important changes to the roof wing/spoiler for the results to have turned around so.

I bet (one dollar) based on my own experiences, that the roof garnish now has an air-gap between it's leading edge and the cabin roof.

This is not one of the Texas Tech papers, apologies to anyone I may have mislead.

I should note that the roof garnish has been reported to be 24"-32" not 6" deep.
