IF the coefficient for the round shape was 1 (it must be less, but follow along), the coefficient for the airfoil is .029? Seems too low, even for a section of a chord? Someone has some numbers, right?

It must?
Aerohead would have to give any exact numbers from his source... But Cd of an infinitely long cylinder moving at low speeds through air is typically given as 1.2. 1/35th of that is .034. That's in the right realm for a streamlined body.
