I don't know how you get that final conclusion. Why do you think the Red Bull is always much faster in qfy then than the race?
Why does that gap dissapear on full tanks?
Even at this track where the DRS was used a hell of a lot less where you could run it where you wanted RB had plenty in hand. So that kinda negates the discussion that RB's dominance was lost on the sunday because of less DRS use.
EBD, well I suppose it depends on how much fuel it uses extra compared to non use? Could they be slightly heavier in fuel to run it?
I personally just think they have built a great all round package and removing the EDB will hamper them but not enough to stop them winning races. They might just then win 9 instead of 12.
I still fancy Vettel to break MS's record this year. So far no one seems to know why the red bull has such an advantage on saturday.
obviously there is a possibility that I am completely wrong
however, it all adds up nicely, at the start of a race, the car is something like 140kg heavier than qualy hence a much lower ride height, the lower ride height may actually not be as efficient for the aero set up the RB has.
Why is the RB not as quick (relatively) on Sundays, well apart from the above, the DRS can not be used anywhere near as much meaning the RB has more drag for more of the lap. Basically the car has too much down force (and drag) during a race.
edit: sorry I see you tackled this and I agree with you on it. It must be because of the change in ride height, probably means the front wing becomes sub-optimal.
The thing is, I can't recall seeing an RB disappearing into the distance during a race.
