Your opinions sound like you have ruled out all but the slot/vent design. So, smikle has actual data and you tour opinion is unswayed. How about McLaren or Ferrari with vast CFD and wind tunnel research efforts, they have not evaluated the slot/vent design and decide to go with different designs? Wouldn't it be more logical to think that the top of the nose is not that influential to the aero design and that there is no design that stands out above all others?
I was the first to applaud n smikle for his efforts, but I don't think anyone, including n smikle himself would say they are definitive or actually prove
anything in particular. You could take them as "proving" there is no air dam if you like, but I didn't go there because he told us it was a "rough and dirty" exercise and I appreciated it for what it was. Also he did not model the "fences" on the sides of the RB8's hump, a major component. This is not a criticism of him or what he has done. He told us what he did and what the results were. I think it was great, for what it was.
McLaren has a completely different aero concept for their cars, so they didn't have a "hump" to have to mitigate.
I have pleaded
with people, time after time after time, to understand that the top of the nose is (relatively) unimportant.
What IS important is that the top of the nose be designed in such a way that it not mess up parts of the car which ARE important.
In comes this "hump" necessitated by the new rules and the desire to keep the nose as high as possible. No one
would have it there if they had a choice. But since it is, and since it is right in the middle of the critical area between the front tires (messing up parts of the car which ARE important), how are you going to mitigate its negative effects as much as possible? Newey made a slot. Lotus and Caterham made a big dip. All excellent solutions. I am not impressed with Ferrari's "worry about it later" hump. But I am sure they will change it at some point.
As far as McLaren and Ferrari not choosing the same solutions as Adrian Newey, in general? That hasn't worked out too well for them in recent years, has it?
