It is after all, all circulation. The descriptor (Bernoulli) at 0A is negligible. That is the problem I have with it. Volume (circulation) is only drag until the LE rises relative to flow, (for all intents and purposes).

A mental image I use is that the wing is an expensive air compressor. Blow on your hand, there is a rise in Pressure. It isn't contained, and nothing happens to imitate actual work. That is why, to me, Ground effect is a critical concept for the novice, one uses it (instinctively, one hopes), for a lifetime. The deck is a dynamic "container", and gives a freebie in "Lift".
Another is that I present the a/c at speed as a ski boat, "Planing" on the dense water, oblivious to the "top" of the "wing". I have set up a complicated model in the tunnel that is two "layers", a dense lower layer, and a very LP "Upper". If separated successfully, the "wing" needs no incidence at all, it rises magically.

Well, Newton is my preference. I've seen diagrams of Bernoulli with thousands of little arrows, but in the time it takes to get anything out of it, Goose has kicked the tires while Mav lights the fires, and they are heading downtown for a knife fight.
Newton would have loved to fly, but other pilots might have avoided him, that is another thread, (for the National Enquirer). Or The Guardian.

it has been fun, take care.
