Thanks Poilou for the the reference, the 3dvf review was instructive !

So I did a quick try in viacad, and the fact that I wasn't able to cross over the red line make me thing that was maybe the problem in MoI too.
Indeed I was able to come very close from what viacad can do on this particular shape -> 0.425 was the limit I find for this wing.
