OK...thank you for taking the time to write that up.
So, not too oversimplify, but is it safe to assume then that the differences in stall sequence relating to rectangular, tapered and elliptical wings is in turn related to the differences that exist in the way each of those wings generate vortices (and other disturbances)?
It's because of many things. For example, since tapered wings experience lower Reynolds numbers as the chord decreases... etc.
But if you're looking for a generalization, it's because of the shape of the wing.
