Agree. Still on the same train of thought about the outer horizontal flap?
The small flap attached to the endplate you mean? Since the endplate is now fully closed, there's no seperation between different gradients of high pressure air coming from the elements. I now think it tried, in the previous wing's incarnation, to "downwash" airflow attached to the outside of the endplate, which sent it right into the outer edge of the last elements, outwashing it there. Probably the biggest issue there was mixing low pressure airflow the endplate with high pressure air from the outwash of the elements. They now clearly seperated those 2 flows. It also looks like I underestimated the importance of the vortex it created, speeding up airflow and further seperating flows.
But I could be wrong. I spoken with others and nobody is really sure. I think with further updates around that area it's intended purpose will be further revealed.
