In general, the experts are right: there's an angle of attack beyond which a wing stalls and makes a lot more drag and loses lift. Every wing and installation is different in what that angle is, of course. It's easy enough to determine if a wing is stalling: just install a bunch of yarn tufts on the underside and see if they are "luffing" or not.

I have yet to see anyone even come close to an optimal wing in CAM so far. However, that doesn't really matter because with the current rule set one can easily make more rear downforce than can be balanced out with the allowed front splitter and dive planes. In fact, I would consider moving the rear wing as far forward as the rules allow to try to distribute as much downforce forward as possible. It would look goofy as hell, but that's a function of the current rule set. I agree that CAM should not allow wings, but that ship has already sailed.
