Aerodynamics teaching at college level, where lift calculations must correspond with the real world, disregards hump theory because it is clearly false, but we can reasonably assume that most who have studied aerodynamics in college were previously taught hump theory in earlier schooling and now know it is wrong. Perhaps it is because higher level teaching involves a complex analogue based on the mathematics of electromagnetic induction, and though it produces useful mathematical results, the induction-based reasoning seems a bit obscure, and not clearly credible. Wings must lift by accelerating air downward, in accordance with Newtonian principles, but air seeking equilibrium recirculates upward around a wing, even ahead of it, in response to the pressure difference created. Wing forward movement intercepts the rising air momentum, so that lift is equal to the rate of downward air momentum produced plus the rate of upward air momentum intercepted. With very long wingspan, these contributions to lift become nearly equal.
Shorter spans lose more upward recirculation around the ends.
