(You can see from Fig. 13 that there is more variability in the pressure over the notchback and fastback shapes, but it doesn't tell you anything about the relative difference in average pressures between the shapes).

Edited to add: Also, notice the drastic difference in front lift between the squareback and notchback/fastback! This is an excellent illustration of shape changes at the rear affecting flow at the front.

2nd edit: Ha, just realized I'm an idiot--you probably meant the whole page of illustrations that includes Fig. 11-Fig. 13. Disregard!
No you're right - I did mean Figure 11 not Figure 13.
