Quick calculation as I'm busy, but with some rough numbers. Ignores drag from rolling resistance and gravity, but these would be negligible change.
Speed in m/s so 15mph is 6.7 m/s which is about my average speed. Assumed cdA of .28 reduced to .24 only gives a 9w saving, which is 0.04 is very optimistic. So 0.2 cdA reduction gives a saving of 4 Watts.
Happy to be corrected if I got the numbers wrong.
