I feel like they'd have to be closer together to make use of the boundary layer effect... They just seem to be far enough apart that they'd induce more turbulence by separating what would normally be a "sheet" of airflow into a largely serrated cross section.

I could be wrong, though. I'm not up on the finer points of aero, yet.
