    Have played around with "number of points" in Javafoil.

    Puzzled as the difference when you compare the same foil with original, 201 and 1001 points differs a lot.

    Also some profiles like NACA 2512 differ more, and other like H105 less.

    The more points the higher Cd. Which one should I trust?

    Probably I should compare different profiles with same amount of points. Still remains which one is closest to IRL?
