For a 20% and 22% thick airfoil the NLF420F/NLF422F has 4-5 drag points less then the next nearest airfoil, in fact the NLF420F is tied with the AS-NLF15 for lowest drag point total (with a CL around .2) with 35 which is surprising since it is a 20% thick airfoil. The NLF422F has the lowest drag of the 22% thick airfoils with 37 drag counts. The AS-NLF15 has the lowest drag of the 15% thick airfoils with 35. The AS5048(AS50-18) and the AS-NLF18 have the lowest drag of the 18% thick airfoils at 38. The NLF425F had the lowest drag of the 25% thick airfoils with 42 with a few other airfoils at 43.
This data makes it seems clear that most of the airfoils I tested aren't designed/optimized with X-foil as improvements seem possible.
I increased the thickness of the airfoils with X-foil and the LE radius seemed to be increase as well so I think some of the 20-25% thick airfoils would have less drag with a thinner LE.
The Riblett 40 series performed poorly with flaps but the other Riblett airfoils were fine.
I tried different LE radiuses and cambers for the NLF420F and the NLF422F but didn't get any improvement.
I couldn't get the data to format properly so see attached document.

This data makes it seems clear that most of the airfoils I tested aren't designed/optimized with X-foil as improvements seem possible.
I increased the thickness of the airfoils with X-foil and the LE radius seemed to be increase as well so I think some of the 20-25% thick airfoils would have less drag with a thinner LE.
The Riblett 40 series performed poorly with flaps but the other Riblett airfoils were fine.
I tried different LE radiuses and cambers for the NLF420F and the NLF422F but didn't get any improvement.
I couldn't get the data to format properly so see attached document.
