There is an awful lot going on at the front of the floor, very broad top section (fairly uniform in height); then starting at the outside there is the pair of strakes with two further (longer) strakes neither of which has a sharp edge at the bottom, the inner of the two has a very large curl (is this to contain and boost a vortex inside the tunnel?). On the side of the centre section there are a couple of interesting looking details (almost ramps built out from the sides of the tunnel).
You mean the plank area? It's hard to make out the details, there's no plan view, and always something obstructing the details.
The plank area is the closest part to the floor, wouldn't the air there be subject to the greatest ground effect?
The outward curve of the inner strake flares out near the trailing edge, I suppose they want to start the vortex as far back in the floor as possible so that it doesn't break down at the throat of the tunnels.
You can see that where the vortex forms would have a clean shot to the diffuser.
