PEOPLE listen up: concave pockets facing forward DON'T act as parachutes because one of the differences is, there is a ginormouse AFTBODY right there. Parachute drag is from the high turbulent flow in the wake because there is no AFTBODY to promote orderly "closure" of flow.
I guess we'll just have to disagree on this point. Go to this page and compare the "prism" to the "bullet." Shape Effects on Drag Contrary to popular belief on this forum, the shape of the front most definitely makes a difference.
