the drag resuls are pretty much as expected. while details may vary a full belly pan seems to decrease drag and lift.

what i find strange is the increase in lift caused by the front and rear pannel, and than the spectacular decrease caused by the center pannels.

i wish they'd tested them separately, because the numbers seem to sugest while they only cause a minor decrease in drag they cause a decrease in lift large enough to cancle out the front and rear increase... but one cannot conclude if they do this on their own or together with the first pannels.
