Chris... the baffles are an impediment and, even if not, diffuse the flow. You do not want to angle the lip downward either as this will break the pattern of flow. You are missing the point here my friend. Water flow needs to be focussed and horizontally shot across the surface to make this long rolling flow pattern.
Your baffle instead is nothing more than and overflowing dam. Indeed, do experiment/try this my friend... even take some clamps and a strip of plastic and rig up a small temporary lip to the overflow side of that baffle. Its tough for both of us here perhaps to explain via text. bummer
do take a stab at it and holler back. Take pics too if you can
