I have looked into it and it looks like you were correct. I have implemented the changes in my version, but I want to discuss the results with Aaron before merging the code. If that can help I have compared the results with the ones obtained from http://www.airfoiltools.com/airfoil/naca4digit.
At the moment there is still a significant difference between the module and the website results (error of 1e-2), for extreme cases like a for the NACA9930 wing. Classical NACA profiles like the 00xx, 14xxx, 24xx and 64xx series should be precise enough to work with.
