Well there seems to be a communication problem 'cos you said:

In any event, in light air, a big round section with a relatively
flat entry will keep attached flow and build up much more power
than a draft forward conventional airfoil shape.

I saw the "big round section" and "much more power" while you were
saying that flatter at the head was no good.

No, I am not saying that and never did. I had the (perhaps mistaken) impression
that this discussion was about
1- variation in chord depth from middle to upper sections
2- where the best point of max draft
3- entry shape, which is a partially function of #2 above.

Would it be too much trouble to stick to one of these points?
