First, Tami, that kills me, glad somebody said it (42..love it)
Second, I didn't read more than 30% of those long posts, I don't have the time (or attention span). Like my boss says, "get to the point".
Tami said it once, I said it once, read a Marchaj book, he's not written the "definitive" books on the subject for no reason.
I deleted my post explanation here, b/c.... I'm tired and don't feel like finishing it now.
In short, the circulation effect accelerates the air on the lee side in comparison to the windward side. SINCE THE LEEWARD FLOW IS FASTER, THE PRESSURE EXERTED (BERNI) IS LOWER ON THE LEE SIDE THAN THE WINDWARD SIDE. Berni is able to tell us the pressure differential b/c of the differing velocities. Berni, then tells us part of the lift coeff.
This guy uses the same type of information as Marchaj.

He did wind tunnel testing with pressure readings. It's hard to argue with numbers.
As he explains it, the jib pulls 4-5x harder per in^2 than the main does. The jibs main purpose is, however to aid in keeping flow attached to the lee side of the main thus reducing drag and increasing efficiency. It does decrease pointing ability, however provides quite a bit of driving force on reaches.
Was I pissy and terse, possibly.... am I about to get done with a week of AF inspections w/sh*tty inspectors and bogus findings... yes. Have I worked 50+hrs in 4 days and only had ~4-5 hrs of sleep/night... yes. I'm going to bed.
p.s. Under the "fallacies" section, he kills the Coanda argument.
