So they needed mediums to run the amount of miles they wanted to and it had nothing to do with the speculation started by the Sky sports chearleading division of mercedes that mercedes were running that tire to gain an advantage from knowing all they could about that tire.....
So do you mean to say, having run 100s of miles on those tyres, lap after lap and collecting the data, wouldn't have helped them understand the behavior of that compound, more than others have?
Anyways, time will tell the answer about whether W07 has any advantages on Mediums, compared to the competition or not. Starting with Bahrain, a track that puts enormous energy into the tyres being a power circuit. Ferrari having chosen 3 sets, would definitely seems to be using it for the race. So that will provide a picture.
I will be curious to hear next set of excuses and, see the LIGHTENING starts of Ferraris, which will be useless on this circuit if they do not have enough in them to keep the Mercedes' behind.
