I think James probably touched on it very well there in terms of it not being a change of regulation; it's a realisation. The things we were doing, that type of interpretation is not legal. I think the difficulty the FIA had is that the protagonists behind raising this issue were threatening to protest the cars and that was the difficulty they had. They couldn't ignore that and once they were made aware of the technology I think they started to sympathise with the view that the people who were upset about it had, because the FIA didn't discover this by themselves, they were alerted about it by a team. And once that ball started to roll, they probably had little choice but to decree what should happen. If they hadn't have taken action, then it sounds like some teams were going to protest the situation to get clarity through the stewards and that wouldn't be very good for Formula One. We want to avoid that at all costs because I know from experience that the stewards would find such a technical argument quite difficult to resolve and it would probably end up in the appeal courts again and that's no good. I think it's probably being dealt with in the best possible way but what we need now is absolute clarity on where we're going with this and I think having the exhaust moved next year is very important because we don't want this to end up as another argument of the type we had about traction control: what was traction control, what wasn't traction control, what you could do, what you couldn't do? We want clarity because, as you know, the traction control issue has not been discussed for several years, and we don't want to have the exhaust blown issue being discussed and being a major distraction to what we're doing. So we will cope – I think we will all cope this year. It will make a difference to the cars. We've got a new floor coming at Silverstone which is designed around that technology. We've got to decide what we're going to do now but I think having the exhaust moved next year should bring clarity to this area. But there will be something else round the corner, as always in Formula One.
Yeah, we have invested a lot of money in development and research on this special exhaust system. Okay, the important thing is, as Ross just mentioned, the clarity in the regulations, and regarding the mapping, we rely on Ferrari, because they provide us with the engines. It's difficult to estimate the performance loss we will see in Silverstone.
