Here's some info to use for an edumacated guess:

According to:

Audi improved the Cd of the A4 with a patchwork of panels applied to the underbody. The sum difference was Cd -0.019

Assuming my continuous smooth under tray achieves at least that difference in Cd on the Blackflea, the rolling & drag spreadsheet tells me I should see a FE improvement of 4.6% @ 20 C @ 55 mph

EDIT: that's a slightly conservative estimate, since the Audi calcs apparently do not include the large front panel.
