Let's go with the Fairies theory. The rest of this seems too much like work.
I curse all of you to a 3 hour presentation by a CFD new grad on his/her wonderful discovery ( a change in the 3 decimal place of a 2nd order coefficient) and how this will make fantastic improvements in the accuracy of their predictions. This meeting will end like all such meetings when the person next to you, who was asleep and drooling on your shoulder, wakes up a points out to the presenter that their changes are still well within the margins of error.
Most of the equations cited in this thread are best used for illustrating the physical phenomena that produces lift. Except for some limited cases they are not very good for predicting it.
Given some good test data I think I could write some equations to predict lift in terms of Fairies.
