Kevin,Thanks for your injections of current data.Do you have an opinion of Mair's taking the boattail's convergent angle all the way to 22-degrees? All of the pioneering work of the 1920s and 1930s arrived at less aggressive angles for aftbodies,however,many of the Cds developed in those early investigations failed to hold up in more modern tunnels,and it makes one ponder,whether or not more can be done with less.I'd be very much interested in your insights.Thanks,Phil.
