It's not even really a setting. I've just looked closely at mine. From fully locked down you can pop the left side and the visor distorts a little bit as that side pops off the seal but at least on mine, there's no visible space between the visor and the seal. Also, the ratchet mechanism on both sides of the helmet remains in the fully closed position.
Having tried it on the road in very heavy rain, just cracking the visor did nothing to stop my spectacles from misting. I then had to open it to the first notch which even on a new 2013 GS which has good aerodynamics, resulted in my spectacles becoming covered in raindrops.
I suspect that you might be able to get some airflow in the bottom of the visor when it's in that unlocked position if you were to loosen off the pivots on both sides and move them slightly forward on the shell. However, I think that might well compromise the seal at the top of the visor and allow the ingress of rain onto its inside face.
Oh I wouldn't open it in rain but it is called city setting. It does let air in but it is a very slight crack. I haven't tried mine in wet weather but I would imagine nothing more than vents would be the best idea...

knows that riding with your shield open even a bit in the rain results in water running down the inside of your shield and water all over your glasses, which is just as bad for visibility as fog. As I said, I've never had a helmet that flowed enough air to keep my glasses from fogging (with the shield closed) in rainy weather. Thus the desire to find a product that would keep my glasses from fogging.
