I've added the new drag table # 14 which is based upon Wolf-Heinrich Hucho et al' SAE Paper # 760185,from 1976.
This work applied to the Golf-1,Scirroco-1,and Polo-1.Since these are 'real' cars we see that they respond differently to the rear slope compared to simple, crude test models.
I've included a more full explanation of the work in the preamble above the new table up at the 1st page #1 permalink.
You can see the origins of the 'Template' taking form.
