Raikkonens tyre/pit stop strategy was identical to Webber's. He stopped on the same laps and put the same tyres on. He maybe just isn't isn't used to driving to preserve the rubber?
Sorry I had a "senior moment". He was on the same strategy as everyone else then and was still slow! Why complain? Imagine the bigger train he would have created if he was on the slower hard "soft tyre". His speed would have mean't even the Caterham's would have been on the Kimi train
