Not at all, very easy to make your car 30kmh faster on the straights by taking DF off, but there's a reason top teams don't do it.
If the reported fuel issues are true then removal of DF is a way to save fuel with the by product of high speeds on the straights.
I'm not buying the slow - fast - slow theory because, if you do that, you're giving the car a breather every 1/3 of a lap and so not properly stress testing it.
Yeah, but then we are talking about special low df packages, and I don't think Ferrari did this or it would have been reported. By keeping the same package and just taking out wing angle, I don't think you would suddenly gain 30 kph on the straights. But I could be wrong
