I too was a little surprised to hear that. They have a lengthy article with charts and graphs discussing how they choose the spoke counts for wheels and their goal is to never make a new wheel less stiff than the one before it. You have a few factors affecting stiffness such as the rim itself, bracing angle (which will vary with rim depth), and spoke count. Turns out, all things considered, Zipp says their 24spoke 303 is 8% stiffer than their 20spoke 404.
