I saw thoese, its partly the reason I was envisioning about a 5 degree angle on the 4th (diffuser) section. What I haven't seen is anythign saying if its better to have the sections in front of that parallel to the ground or pitched in one way or another.
Right now for simplicity sake the plan is to have a flat bottom from front to back. Here's a bit of construction detail for section 3 (the main underbody & side skirts)
