What I am taking away from this is the acute angle at the rear would be 2x(22 or 23°) or, on average, 45°. Which is what I use on the 3-foot tail in the Collapsible Boat-tail thread.

When you truncate, doesn't a recessed box section work like a half-tonneau on a pickup, and further reduce drag? Is there a rule-of-thumb for determining the depth of the box?
