I made a visual script in Rhino that used the actual mathmatical formula for NACA 00xx series foils.

If you strictly use the formula, it comes out with a nice naturally 'rounded' front edge, definitely not sharp, but also with a continuously changing radius. Perhaps the front radius rule applies only to the radius measured at the very front point.

sorry for the large pic
