How can it not be included but figure into which implies included in?

The coefficient of lift is merely a measure of how much the estimated lift the wing will develop vs. the experimentally tested lift as measured. A measure of this doesn't make too much sense when dealing with hard facts, as it is a prediction based on prior performance

Woah, this is an accepted theory, though not law due to complexities far beyond the scope of what you posted. It is an accurately tested and accepted theory where [Cl = 2 pi AOA]. Even so, the "real Cl" as you put it since this is only the "tested" one, still goes up, even with the newest Cl theories. There has not, to my knowledge, been a theory that proves Cl not going up in ground effect. Though I would be glad to enlightened if there is one.

Here is an advanced theory for a "more accurate Cl" if you would like to see some advancing theories on this topic:

Otherwise, nice post, the methods aren't unconventional they are just the other factors that cause lift: impact, bernoulli, and deflected air.
