Not repeatable therefore not real useful for comparison. The guy should
rotate the airfoils to minimum drag each time, otherwise, he doesn't know if
they are in comparable positions. It's also a shame he didn't replace the
airfoil with an equal-flow-area rectangular shape. As a result he produces
confusing and misleading results, inferring that a round shape has more drag
than a rectangular shape!
