I'd bet a dollar that middle spoiler is doing something... watch the rear 1/4 panels... the tops sweep right into it, and chances are, the flow hasn't detached at that point, so it's making contact w/ the duckbill.

How much or little effect it has is hard to determine, but I can almost guarantee that it's catching flow off the rear 1/4's.
