Isn't that the reason for reducing the drag coefficient through wind tunnel testing of different shapes at various speeds ? Feel free to leave out wind as a complicating factor, as I certainly have.

IOW, drag (and design of a bike to minimize it), has dramatically increased at speeds of 25 mph and up. So the faster riders are "getting more advantage" from the design. I don't honestly know how much "time saved over a course" either group is experiencing. It seems you do. What is missing in my thinking on this ?
