Sorry, I kept with Hucho's Figure numbering from his book, and did not cite Buchheim's figure.
The figure has two vehicles stacked to the left, the upper depicts a fastback wake, the lower, a squareback wake.
The table to the right gives delta-Cd along the left margin, and angles ascending from zero to 90-degrees, left to right.
Five different aft-body proportions are listed, 9%, 18%, 27%, 36%, and 45%.
From the five curves the drag minimum 'buckets' are leaping off the page.
13.3-degrees, 15.3-degrees, 17.4-degrees, 18.5-degrees, and 22.5-degrees, respectively.
I won't be back until next Wednesday, but I'll snag that number.
