Now that's a bullsh!t explanations if ever there was one. I guess he'd like everyone to look at his notebook instead of at the photographic and video evidence. 
Let me see... so the wing goes DOWN when the car is at speed.... from his explanation the wing should be going down while they're under braking... you know cause the RB rear is so high. But wait, I see the wing actually come UP during braking.
I guess Newey is as much of a magician as everyone says he is because his aero designs can alter the laws of physics.
I know this is going to come across as a stupid fanboy trying to get people to lay off his team but i genuinely dont get it.
Isnt the car under the highest load at high speed? Thus pushing it down as high pressure regions develop on the car from a large volume of air travelling over it while relatively low pressure regions are created under it, duckling it to the floor?
So under breaking, as the car slows and less air is travelling over it's body the pressure should decrease and allow the car to rise?
There's a natural tendency for cars to dive down in the front when braking since most of the braking force is done with the front wheels. Not as pronounced in an F1 car of course, but try it at home. But the issue here is that this has nothing to do with braking or the entire car rising or falling as Horner is suggesting with his "notebook"
There is clear photographic evidence with a computer ray traced outline of the nose of the car flexing two or three degrees... clearly visible with the the angle of the front wing endplate tilted down by those same couple of degrees... no amount of suspension difference would cause that part of the body to actually TILT.The part in question is one piece, we've all seen them replaced hundreds of times when they get broken. That part of the car would never deform/flex or change due to suspension geometry magic, it's a solid piece. So to have this evidence of that portion flexing a couple of degrees is something they'd need a hell of a lot more than a notebook demonstration to answer.
More power to Red Bull, they figured out a way to beat the system, it's the "Wall Street" way, so let them enjoy it, but don't sit there and insult everyone with ridiculous explanations of what they must be seeing.
Eventually other teams will do just the same thing, (that I'm sure of) and perhaps then the FIA will investigate.
