We've had countless meetings with the technical directors of every team, and we have had a whole range of proposals from what appears to be a huge amount of downforce to a very low level of downforce, but it is all based on the premise that we will have a significant increase in mechanical grip. So what we have ended up, inevitably, is somewhere in the middle.
It is incorrect to say that the anticipated lap time improvement will all come from downforce, because it simply shouldn't be. The whole idea is that half of that will come from mechanical grip, and the other half will come from aerodynamic downforce.
One of the things that we have been talking all along is the fact that we must not make it more difficult to follow another car, and that has been one of the underlying principles. So, we've done I believe the best we can, given we have to take everyone's views in to account.
